Old sci-fi movie and similar titles

[wositelec]

I'm looking for old SF movie from the 1950s or 1960s. A group of astronauts or researchers travels to Mars or similar planet. Strange things started to happen, and an invisible force was present. At the end i remember someone said that it was their alter ego that was causing all the problems. What could the title be?

It isn't "Forbidden Planet". If you know my movie or similar titles - let me know, please.

Maybe you’re looking for Journey to the Seventh Seventh Planet.
