Marooned (1969)

Flight Surgeon: [regarding the earliest possible time for rescue] You know of course that by 22:31:06, the crew will be dead. There's not enough oxygen left for three men to live that long.
Charles Keith: Well what about... two men?
Flight Surgeon: We don't figure that way, we plot total pressure against total use.
Charles Keith: Is there sufficient oxygen for two men? For one?
Flight Surgeon: [long pause] Two might just make it.

Clayton Stone: Jesus, fifty-five minutes... We'll be pretty cold by then.
Buzz Lloyd: Well, one of us's gonna have to go. I mean uh... that's what we're talkin' about, isnt it? One of us goes and the... other two stay. What... what are we gonna do?
Clayton Stone: Alright look. Let's do this scientifically: two big guys throw the little guy out, okay?

[Keith is pulled over by the Highway Patrol for speeding]
Charles Keith: Look, I've got to get to a telephone!
Texas DPS officer: Will you shut off your engine please?
Charles Keith: Officer, I'm Charles Keith, head of Manned Space!
Texas DPS officer: I know who you are. You have no brake lights. Your license is expired. You may be able to get to the moon, but mister you're a menace on the highway!
