Similar movies in deep space?
I'm actually watching some old and classic sci-fi movies, and I've strongly enjoyed two of them in particular: "Forbidden Planet" and "Robinson Crusoe on Mars".
Now, I'm looking for more from the 50s/60s/70s, but with the same concept: on a far away / unknown planet and/or in deep space.
I've read many lists of good old classic sci-fi, but most of the movies listed are using the aliens/monsters invasion on Earth formula.
I've also re-watched "Planet of the Apes" (1968) and "Journey to the Center of the Earth" (1959) which takes place on Earth of course, but overall has a very "unknown planet" feel in it.
So, do you know movies with that formula that I could enjoy?
