in what american film does a middleaged guy go to/dream he is in a biosphere on Jupiter. 1970s/80s?

Question

No one believes him. I think when he is on Jupiter he talks to a woman that you never see and he is quizzed about humans.

I remember his wife has a car accident and thinks he is mad.

Sounds bizzar but a good story line.........honest

Answer 1

I think you're talking about Slaughterhouse 5. Based on the Kurt Vonnegut novel. But the planet was Tralfamador, not Jupiter.
