This Movie Sucks!

• Ed the Sock is a puppet, created and voiced by Steven Kerzner. Ed has a scowl, a cigar sticking out of his mouth and a rough, gravelly voice. The show is alleged to be set in his apartment or basement, although as Ed himself has noted, everyone knows they are in fact shooting everything in a studio.
• Liana Kerzner (stage name Liana K) is Ed's co-host, and is actually the wife of Steven Kerzner. Unlike the other characters, she was never referred to as a guest, likely due to her previous role as co-host on Ed & Red's Night Party.
• Ron Sparks is a comedian who has appeared in almost every episode alongside Ed and Liana, and in voice-overs during the movies. He sits behind the couch, usually alone at Ed's bar accompanied by a drink, and is known for making off the wall comments and frequently saying "I'm Ron Sparks". In one episode in which he was unable to attend, the rest of the cast try to find him an understudy, with Max Brand eventually earning the coveted title after introducing himself by loudly announcing "I'm Ron Sparks, but I'm colored!".

• Andrew Young is a writer on the show who has been in several episodes. Andrew dressed up in a starfish alien costume at Anime North even though he didn't want to because Ed insisted. Ed has also gotten Andrew to dress up as a two headed monster and a mummy, with Andrew frequently yelling at Ed that he hates doing it. Andrew is an internet radio host for Geek Hard Radio and a filmmaker. Ed broadcasts one of Andrew's short films at the end of the third episode after Andrew agrees to dress up in costume, or at least find someone else to do it for him.[6] In another episode he auditions to be Ron's understudy, but he loses to Max Brand.
• Larissa Drobot is a student intern who often helps out with projects in the show. In The Manster episode Liana did special effects make-up on Larissa's face. In the Wild Women of Wongo episode she shared a story. In the fake telethon episode, she tried to have her birds do some tricks.
• Amusing Duck is a cheap foreign import toy which the cast found in a novelty shop. First introduced in The Manster episode, the duck is capable of excreting plastic eggs out of a plastic flap representing the bird's buttocks, with the toy's box stating in broken English "Lay egg is true!". It later appears after the showing of The Killer Shrews, after it bashes through the wall in parody of several scenes in the movie, although it was quite clearly pushed through by Andrew Young.
• Naked Dave is a friend of Liana's who likes to take off his shirt for no reason, which Ed hates. He is very proud and protective of his sports car (to the point where he kills Steve the intern after Steve threatens to egg the car). Naked Dave was a guest in the episode The Master, but at the end of the episode he is killed by Roninja. He does, however, appear later during the fake telethon to fight "Cheap Bastard Disorder".
• Bandito appears during the Mexican movies double feature special, after Ed invites Mexican wrestler Bandito on the show as a guest because he is the closest guest he has to a real Mexican person. Despite being a luchador, his only piece of costuming is his wrestling mask so Ed makes fun of his T-shirt and shorts. The first movie features The Robot vs. The Aztec Mummy, so Liana dresses him up in a robot costume. Ed later sends him to the most dangerous neighbourhood in Hamilton to pick up some Mexican food. He is then attacked and possibly killed by Lake Erie Pete after Andrew Young is supposed to fight him dressed as the mummy but leaves. He is also later seen in the fake telethon episode, manning the phones.
• Max Brand was a frequent guest on Ed's old show. He appears in the telethon episode as a dancer who also works answering phones on the phone bank. In another episode he returns to audition to be Ron's understudy and wins the part.

• Charlene Zacks was a regular on Ed's old show who Ed always puts down. They frequently pass insults back and forth with Ed coming out on top. She was a guest in the premiere Gorilla episode of TMS! but has not been back since.
• Steve is another intern who enjoys eating bags of potato chips. He is killed by Naked Dave the zombie after threatening to egg his car, as instructed by Ed. Steve never talks.
• Emily Schooley is shown in the fake telethon episode, where she plays a phone operator coerced into helping Ed and Liana out. She sometimes works behind the scenes as well - in the Roninja episode, she did Naked Dave's makeup as well as working as set continuity/PA. In real life she is an actor and improviser.
• Roninja is featured in the episode featuring The Master (about an American Second World War veteran who was trained by the ninja). Ron Sparks tells the legend of the Roninja, a half Ronin/half Ninja who became a crime fighter after his parents were killed by "the Yakuza gang". After the story Sparks suddenly disappears making it appear very possible that he is in fact himself the Roninja. Ed keeps saying that the Roninja isn't real, but Liana points out there is a Roninja page on Wikipedia. It is obviously Sparks playing the Roninja (he has Spark's voice and drink), but it is not shown whether he is actually supposed to be the same person. At the end of the episode Roninja kills another guest, Naked Dave.
• Lake Erie Pete is shown in the Mexican movies episode, during the Haunted Swamp feature. Sparks tells the legend of Lake Erie Pete, about a man who becomes a crime-fighting swamp monster after his parents are killed by one. The story is almost exactly the same as the Roninja story from the previous episode. After telling it, Sparks again disappears then Lake Erie Pete shows up in a cheap Creature from the Black Lagoon mask to ambush the Robot after the failed Robot/Mummy fight.
• Crackers the clown appears during the fake telethon episode, during which he plays a song on his accordion and also plays back-up music for other performers to dance to.

The series won the 2011 Canadian Comedy Award for Best TV Show.
