Robert Rodriguez's unrealized projects

According to Mike Allred, he was first offered the chance to sell the movie rights to Madman in 1992 (he has not said who made the offer, only that he declined). Since 1998, Rodriguez has owned the film rights to Madman. Both he and Allred have given numerous signals as to the start of production over the years, but with no result. Although both have been occupied with other projects (Allred was instrumental in connecting Rodriguez with Frank Miller, leading to the production of Sin City), both have been eager to see this film made.[1] Robin Williams was mentioned as being under consideration for the role of Dr. Boiffard before his death.

At the 2006 WonderCon in San Francisco, Allred announced that Madman the Movie was in pre-production and hoped to begin filming before the end of the year. He teased fans in attendance by saying that the titular role had already been cast, "but I can't tell you who it is yet.... When we announce it, you're gonna be like 'What?', then you'll think about it for a second and see that it's perfect."[2] In 2015, Allred indicated on Twitter that the rights to Madman had reverted back to him,[3] and in September 2019 has stated that he prefers to focus on comics rather than film or television adaptations for the time being.[4]

In 1994, Rodriguez wrote an early script for a third Predator film for 20th Century Fox while he was working on Desperado at the time.[5] Rodriguez presented the script to the studio, but was denied when they realized that the budget would be too large.[6] Fifteen years later, the studio decided to go with his script. Rodriguez stated:

It's the story from that script I had written way back then. They had hired me to write a Predator story while I was waiting to do Desperado back in 1995. It was crazy, this thing I came up with. So then fast-forward to now and, like, six months ago, they found the script and called me up. 'Hey, we want to redo this franchise and we found your old script. This is where we should have gone with the series! We want to move forward.' And that's what we're doing.[7]

In 2009, 20th Century Fox studio executive, Alex Young, called Rodriguez to consider using his treatment to revive the individual Predator franchise.[8] Predators was produced at Rodriguez's Troublemaker Studios as opposed to 20th Century Fox so that Rodriguez had more creative control over the film.[6] It was originally thought that Rodriguez would direct, but on July 1, 2009, Nimród Antal was officially signed on to direct.[9]

In 1995, Rodriguez signed on to direct The Mask of Zorro with Antonio Banderas for TriStar Pictures and Amblin Entertainment.[10] TriStar and Amblin were impressed with Rodriguez's low budget filmmaking, however, he pulled out of the project 1996 due to budgetary problems. Rodriguez wanted a budget of $45 million and the studio only wanted to do a $35 million film.[11] The film was eventually released in 1998, directed by Martin Campbell, who reteamed with Banderas in 2005's The Legend of Zorro.

On the director's commentary track for Sin City, Robert Rodriguez said that he had been attached, in 1997 or 1998, to direct a remake of the 1955 film noir, Kiss Me Deadly. It was to have been produced by Michael Mann. Rodriguez said he left the project because he thought it was "too nostalgic".[12]

In 2004, Rodriguez signed on to direct the film John Carter after his friend Harry Knowles showed him Mark Protosevich's script. Recognizing that Knowles had been an adviser to many other filmmakers, Rodriguez asked him to be credited as a producer.[13] Filming was set to begin in 2005, with Rodriguez planning to use the all-digital stages he was using for his production of Sin City, a film based on the graphic novel series by Frank Miller.[13] Rodriguez planned to hire Frank Frazetta, the popular Burroughs and fantasy illustrator, as a designer on the film.[14] Rodriguez had previously stirred-up film industry controversy owing to his decision to credit Sin City's artist/creator Miller as co-director on the film adaptation; as a result, Rodriguez decided to resign from the Directors Guild of America. In 2004, unable to employ a non-DGA filmmaker, Paramount assigned Kerry Conran to direct and Ehren Kruger to rewrite the John Carter script.[13]

In May 2007, it was announced that Rodríguez had signed on to direct a remake of Barbarella for a 2008 release.[15] At the 2007 Comic-Con convention, actress Rosario Dawson announced that because of Barbarella, production of Sin City: A Dame to Kill For would be put on hold. She also announced that she would be playing an amazon in the Barbarella film.[16] As of June 2008, plans to remake the film Barbarella with Rose McGowan as the lead have been delayed; the actress and director are instead remaking the film Red Sonja.[17]

A second Red Sonja film had been in development for several years. In 2008, Rodriguez and his production company Troublemaker Studios were working on a version that would have starred Rose McGowan as the titular character.[18]

In May 2008, Rodríguez is said to be shopping around a prison drama television series called Woman in Chains!, with Rose McGowan being a possibility for a lead role.[19]

Both Rodriguez and Quentin Tarantino have said that they are interested in making a sequel to Grindhouse.[20] Tarantino said that he wants to shoot an "old-school Kung Fu movie in Mandarin with subtitles in some countries, and release a shorter, dubbed cut in others" for his segment.[21] It has also been reported by Rotten Tomatoes that Edgar Wright may expand Don't into a feature film.[22] According to Eli Roth, he and Edgar Wright have discussed the possibility of pairing Don't with Thanksgiving for a Grindhouse sequel. Roth is quoted as saying "We're talking to Dimension about it. I think they're still trying to figure out Grindhouse 1 before we think about Grindhouse 2, but I've already been working on the outline for it and I would do it in a heartbeat."[23]

Electra and Elise Avellan, Rodriguez's nieces who play the Crazy Babysitter Twins in both films, originally stated their uncle wanted to do a sequel featuring both Machete and The Babysitter Twins, but the latter concept did not materialize with the former's release.[24] In an interview, Electra Avellan discussed a sequel with "Robert mentioned something about the end of the world and Hollywood action films, where we'd be trained in Mexico to come back here and fight".[25]

In May 2007, Rodriguez was in talks with Universal Pictures and Warner Bros. to make a CG adaptation of the 1960s Hanna-Barbera TV show The Jetsons for a potential 2009 theatrical release, while also offered at the time to direct a film adaptation of Land of the Lost with Universal. Rodriguez was uncertain which project he would pursue next, though the latest script draft for The Jetsons by Adam F. Goldberg was further along in development.[26]

Nimród Antal had talked about a direct sequel to Predators and said he would love to do one. Rodriguez has said that he has interest in a sequel because of the large number of potential ideas the Predator planet setting provides:

There are so many great ideas… Just following Laurence Fishburne's character (Noland) around in a prequel would be a great movie. Just the tales he tells in this movie alone, I want to see those experiences… That's why I wasn't precious even about the original script I had, because once you come up with the idea of a Predator Planet, that Predators use as their hunting grounds and humans are involved somehow, the story ideas that you can come up with are so numerous that you can come up with any approach. So we already have several ideas that we can go with for a sequel. They would all be good ideas but we would probably put them together to see which one rises to the top, if we made another one.[27]

In 2010, Rodriguez confirmed that there would eventually be a Predators sequel:

"[The studio] said, 'Let's do some other ones. What other story ideas do you have?'" says the filmmaker. "Because it was like, let's test out the market with this one. They really wanted it to be pretty contained, pretty scaled-back. They didn't want to put too many of the ideas into it that we could save for a second one. So we could see what the appetite was, because the bigger movie would actually be what comes following that. That kind of sets up a new storyline, new location and world, and then you can really go crazy from there."[28]

Adrien Brody also spoke about reprising his role in a possible sequel:

"I think a lot of that is determined by the success of the film. And I don't think that far ahead. The idea of reprising the role and going farther into that character is interesting to me… It would be exciting to watch a character progress or deteriorate. That's exciting for an actor. I thoroughly enjoyed playing Royce. Again, part of the attraction is I'm oddly drawn to material that affects me on an emotional level, and characters that are dealing with things that are challenging that I would question, that I'm not so familiar with. Royce has his emotional arc in this that most of the characters I've played don't come close to possessing. That's an interesting thing to cultivate."[29]

In June 2014, Fox announced plans for a new movie, with Shane Black co-writing and directing, Fred Dekker co-writing and John Davis producing (without the involvement of Rodriguez). At the time, Black said the film is a sequel, rather than a reboot.[30] In August 2015, Davis said the film would "reinvent the franchise."[31] In November 2016, it was explained that since the plot takes place on Earth, the story will be more closely linked to the first two films.[32] In January 2017, it was announced that while the film would acknowledge the events of Predator and Predator 2, it was unknown if it would acknowledge the events of Predators.[33]

In December 2010, the production of a fourth From Dusk till Dawn film was in the planning stages,[34] but further work on this possibility has not been revealed. In November 2013, it was reported that From Dusk till Dawn: The Series had begun production, without any further mention of the film.[35]

In 2010, Rodriquez had plans to make a live-action remake of the 1983 cult classic Fire and Ice, originally directed by Ralph Bakshi.[36] Despite wanting no involvement in the remake, Bakshi agreed to license the rights to Rodriguez.[37] The deal closed shortly after the death of Fire and Ice's concept artist Frank Frazetta. By December 2014, Sony Pictures Entertainment acquired the rights to make the remake, with Rodriguez still attached to direct the film.[38]

In July 2011, Rodriguez announced at the Comic-Con that he had purchased the film rights to Heavy Metal and planned to develop a new animated film at the new Quick Draw Studios.[39] On March 11, 2014, with the formation of his very own television network, El Rey, Rodriguez considered switching gears and bringing it to TV.[40]

Dimension Films had announced the fifth installment in the Spy Kids series following Spy Kids: All the Time in the World. It was under talks to have the original cast expected to return. However, the film was permanently delayed from its intended 2012 production,[41] as the film's stars Rowan Blanchard and Mason Cook, who are no longer kids, were both committing to current projects (Girl Meets World and Speechless respectively), and the planned sequel got cancelled as a result. On June 16, 2016, Netflix and The Weinstein Company announced an animated CGI reboot of the Spy Kids film series titled Spy Kids: Mission Critical, which was released in 2018.[42]

At the end of the first film's theatrical version, two sequels are mentioned, Machete Kills and Machete Kills Again. The trailer for the third film titled, Machete Kills Again... In Space,[43] precedes the second film as a "Coming Attraction".[44][45] In 2015, Trejo told Halloween Daily News that the third film is happening.[46] Machete Kills grossed a worldwide total of $15 million, on a budget of $20 million, making a sequel unlikely.[47][48]

Wallace is set to appear in Sin City 3, to be directed by Rodriguez and Frank Miller. Rodriguez has said he wants Johnny Depp to play the part. Depp was originally supposed to play the part of Benicio del Toro's Jack "Jackie Boy" Rafferty. However, filming of Sin City conflicted with that of Depp's movies. Depp has expressed great interest in being a part of the Sin City franchise.[49] Frank Miller revealed at the 2014 Comic-Con that he and director Robert Rodriguez have had discussions about a potential third Sin City film.[50] Miller said at the event, "So you better show up for number two, or they won't pay for it".[50] Sin City: A Dame to Kill For grossed a worldwide total of $39.4 million, against a production budget of $65 million, making a sequel unlikely.[51]

In May 2015, it was announced that Rodriguez would direct a live-action adaptation of Jonny Quest, with a script co-written by Rodriguez and Terry Rossio.[52] Adrian Askarieh has stated to IGN that the film will be Indiana Jones meets James Bond with a PG-13 rating.[53][54][55]

In July 2016, Forbes reported that the film would start a franchise with Rodriguez and Rossio's script and will be directed by either Joe Cornish, Justin Lin or Scott Derrickson. The film will position Jonny in the film as "Harry Potter inside an Indiana Jones movie" and specifically sets the film up with the potential for spinoffs. The script also took inspiration from a few specific stories and elements in the original 1960s TV show. The site reported that the studio was considering actors Idris Elba, Bradley Cooper and Will Smith for the role of Race Bannon.[56]

In November 2018, Warner Bros. announced that the movie would be instead directed by Chris McKay.[57]

In March 2017, it was announced that Rodriguez will direct the remake of the 1981 dystopian sci-fi action film Escape from New York, with the original's director Carpenter producing.[58] In February 2019, new development surfaced when Leigh Whannell and Luther creator Neil Cross were hired by 20th Century Fox to write a new script.[59]

On March 28, 2017, Rodriguez signed on to direct, write, and produce the film UglyDolls.[60] He was replaced by Kelly Asbury, after Rodriguez left production to focus on Alita: Battle Angel.[61] He remained intact with a producer and story credit.

James Cameron and Rodriguez have hinted that Alita: Battle Angel could lead to multiple sequels.[62] On February 6, 2019, they announced that they have plans for Alita: Battle Angel 2 in the future. The casting of Edward Norton in a non-speaking role as Nova in this film was intended to be a setup for the sequel.[63] Additionally, the uncredited cameos by Michelle Rodriguez and Jai Courtney were meant to set up larger roles in a sequel.[64] In July 2019, Salazar urged fans to buy the film on physical media and expressed her hope that a sequel would be made.[65]

In an interview with BBC Radio 1, Cameron explained the reason for rearranging the film title from the initial source material, allowing the possibilities of sequel titles, "It's Alita, colon, Battle Angel. Because the next one will be "Alita: Fallen Angel" and then Alita... you know "Avenging Angel" and then Alita whatever. I mean, that's assuming we make some money".[66] On December 2, 2019, John Landau, discussing the possibility of the sequel in an interview with CinemaBlend, said the following: "What I think the Alita Army should do is keep peppering our family now at Disney and [let them know] how important it is to have another Alita movie and hopefully we'll venture there one day."[67] The film is listed with losses as high as $53 million, making a sequel unlikely.[68]

At the 2019 Cannes Film Festival, Sylvester Stallone revealed he had plans to reboot his 1986 action film Cobra as a streaming series, say “That (conceit) was what if Bruce Springsteen had a gun? That was rock n’ roll meets drama. That should have been another franchise because that character was so cool. And I blew it. My personal life got in the way. But we’re trying to bring it back as a streaming TV series. Bring out the zombie squad. I’m long gone, but the idea is really good.”[69] Later that year Stallone revealed to Fandango that "I’m talking with Robert Rodriguez right now about Cobra, which looks like that could happen,” and that “It’s basically his baby now.”[70]
