Teenagers from Outer Space (1959)
An alien spacecraft comes to Earth, while searching the galaxy for a planet suitable to raise "gargons," a lobster-like (but air-breathing) creature which is a delicacy on their homeworld.

A '57 Chevy, white Bucks, a Nik-Nik shirt, some Brylcream, and pliable cheerleader...
@countZZero yeah, it’s funny how complete strangers on the internet can see things with an uncanny familiarity.
