Spaceship Earth (film)

Using archived footage and present-day interviews, the film follows the large dome that featured a replica of earth's ecosystem called Biosphere 2, constructed in the Arizona desert. Trying to see if it is possible to establish human existence on other planets, eight "biospherians" go to live inside the vivarium, where they face ecological issues and accusations of cult-mentalities.

On review aggregator website Rotten Tomatoes the film holds an approval rating of 87% based on 105 reviews, with an average rating of 6.94/10. The site's critics consensus reads: "Spaceship Earth achieves liftoff as an engaging behind-the-scenes record of an audacious experiment -- and settles into orbit as poignant proof of the power of a shared dream."[2] Metacritic assigned the film an average weighted score of 73 out of 100, based on 26 critics, indicating "generally favorable reviews".[3]

John DeFore of The Hollywood Reporter wrote: "Using both present-tense interviews and footage from the time, Wolf shows how things nearly fell apart. But he also captures the seriousness of purpose behind what some saw as a giant publicity stunt — and convinces us that this was a one-of-a-kind way to learn some of the things humanity will need to know as this world changes and others are considered for habitation."[4]
