Movie identification: Science fiction movie where people believe they are living on a spaceship but are really on Earth

Question

I don't remember when the movie was from, but I saw it one to two decades ago. I just have this hazy recollection that all these people lived on what they believed was a spaceship. They are supposed to be on a long voyage to some far off solar system, but in reality they are on Earth and are being studied by scientists to figure out the effects of long-term space travel on humans.

I have this visual in my mind of one character sneaking out of the supposed spaceship and that's how the other character figures out they are not on a spaceship.

Answer 1

It sounds like the BBC adaptation of the 1962 novelette "Thirteen to Centaurus" by J. G. Ballard (ISFDB, Wikipedia) which was identified by Stan in the answer to this question.

Answer 2

If you're dealing with a more recent media, Ascension was a mini series on Syfy in 2014 with that plot. The basic premise was that this mission had been "launched" in the 1950's and the government had convinced the participants they were part of a generation ship headed to far off star system. The parts set on the space ship had a very Mad Men esque vibe because these people had been insulated from modern culture and events.

Answer 3

Could it be the "Out of the Unknown" episode "13 To Centaurus"?

"Interstellar travel at sub-light speeds: the enormous distances, isolation from human culture and the aching loneliness of space are enough to drive the strongest personality insane. Better to block all memories of human contact and to program the 12-strong crew to accept only the reality they can see and touch within their spacecraft. But a child born on "the Station" becomes insistent on learning the truth about 'Outside'."

This might be the 1994 film, Terminal Voyage, as per Movie Identification - Spaceship, earth destroyed but not really.

In 2035, global warming rendered the Earth barely inhabitable and its human population is on the verge of extinction. The Earth Federation sends a space ship on a century-long trip to a distant planet Trion which could be suitable for colonization. The eight crew-members come from Russia, United States, China, United Kingdom, France, and Saudi Arabia.

As the ship approaches Trion, the crew wakes from hibernation. They immediately find a decomposed corpse of the Captain in his capsule. The ship's XO, Commander Hollis, assumes command. When he reads a secure transmission from Earth received while they were sleeping, he commits suicide, leaving a note that he "joins his loved ones". The new CO, Lieutenant Jammad, reveals the content of the message: the Earth has been devastated in a nuclear holocaust.

Zinovitz discovers that the ship's systems have been tampered with. A fight for power ensues and Becker, as a representative of the government, relieves Jammad from command. He is soon found dead in a malfunctioned virtual reality simulator. The remaining crew-members suspect that Becker killed the officers and use force to arrest her, discovering in process that she is an android.

When questioned, Becker denies any guilt then sets off the self-destruction sequence. Granier and Han are too devastated to continue and commit suicide with a morphine overdose, and Reese and Zinovitz make it to the escape capsule. As the countdown reaches zero, they find themselves in an underground simulation facility stationed on Earth. There was no space flight – it is their final test, an "extreme stress simulation" scenario which involved the death of the commanding officer and multiple system failures. The crew have only been in hibernation for 6 months, and Hollis, Jammad and Becker apparently knew about the test.

However the nuclear war on Earth was indeed real, and the facility is empty and abandoned. The film ends with a view of a destroyed city, as Reese and Zinovitz look on to uncertain future.

Answer 5

It could be the Doctor Who story Invasion of the Dinosaurs.

One strand of the story featured would be colonists on a fake spaceship heading off to colonise a new world, or so they think. In actual fact, the ship will remain on Earth. The plan is to use time travel to change Earth's history so Mankind never evolved. The colonists will then have a clean green planet to live on.

A couple of clips can illustrate it. In the first we see Sarah arriving on the fake ship. In the second, Sarah opens the airlock.

Answer 6

There was a similar Twilight Zone episode called "Where Is Everybody?" Except he didn't think he was on a ship.

Answer 7

The movie is pandorum. I've been searching forever for the name of this movie as well, but I finally found it.
