Strange and haunting Science Fiction Film

Question

What is the name of this movie:

Possibly filmed in the 70's or 80's, sort of like the movie Silent Running in that it has a greenhouse filled with lots of plants. I only remember the ending of the movie where one man dressed in white stands alone in the spacecraft looking out through huge glass walls (I think like a dome) seeing only space and stars. I think the spacecraft is adrift, lost in space somehow. Anyway this man chooses to remain caring for the plants not really knowing where the craft is going. It is a very haunting tale.

Answer 1

I put together the timeframe, spacesuit, and greenhouse to come up with this suggestion, a great movie - essentially High Noon in space. I think you might mean Outland from 1981, with Sean Connery. Connery plays a Marshall on an off-world mining colony, not a spaceship, who annoys the local company President, played by Peter Boyle. When the annoyances get too deep, since the President is involved in a conspiracy to increase profits, he hires an assassination team to deal with the marshall, Connery. The showdown scenes involve a hide-and-seek in the colony's massive glass greenhouse, which is hundreds of feet high and wide, multiple stories. Outside the glass, of course, is a starfield. The assassins are inside with Connery outside in a pressure suit.

Otherwise, I agree you mean Silent Running, also.
