70s/80s SciFi film where a space-ship has only one rescue capsule, so the crew members start killing each other
I'm looking for a movie that I once saw on German TV in the early 00s. At least I think it was a movie - I cannot say for sure that it wasn't an episode of some TV series. What ever the case, I'll try my best to describe what I can recall about it (spoilers ahead, obviously).
The film is set on a spaceship with a crew of roughly six to ten people. The ship needs to be evacuated, but no rescue mission is possible right now - maybe they are too far away from Earth, maybe their communication devices have failed, I don't remember. There is only one rescue capsule and it might be unclear whether the rest can be rescued at a later time.
Somehow, they determine who will go on the capsule. 944
Maybe there's a logical reason for their choice, maybe they draw sticks - I don't remember. The lucky person is a 30-to-40-ish man who I imagine with a moustache when I try to recall his looks.
For some reason, the lucky person stays (has to stay?) on board a little longer. During that time, some crew members try to kill him, some try to convince him to let them go instead of him, some get killed in other ways (I guess).
In the end, the man with the presumed moustache is the only living person left on the ship when he finally enters the rescue capsule and the movie ends.
One particular scene I remember features a woman trying to seduce the man in order to convince him to let her use the rescue capsule. He plays along for a little while, but he doesn't fall for it and ultimately leaves saying something along the lines of "I will always remember you when I think of something very cheap!" ("Ich werde immer an dich denken, wenn ich an etwas ganz Billiges denke!" in German, if I remember correctly - maybe he says something different in the English version). I think the woman was Black and short-haired, but I'm not one hundred per cent sure with either of these properties.
I may have misremembered some of these things, so don't hesitate to suggest movies that do not match my description in all points.
The movie I am looking for is not among the following ones: Trapped in Space (1995), Lifepod (1993), Lifepod (1981) 1012
