Name That Trauma :: Reader Saraeg on an Old Outer Space Flick

Dear kindertrauma,

I am older than the most recent traumatized citizen, and would like to ask if anyone knows the name of this movie. It is a ‘50s space movie where the astronauts land on some unidentified planet and in just the area where the ship lands, it is transformed into an earth-like atmosphere with the usual plant life.

The astronauts go to explore and find a cave, which seems okay but there is a mysterious curtain of plant tendrils that seem to guard a secret! When one of the astronauts puts his hand through the curtain, he screams in pain and pulls his back and it is frozen! Some kind of aliens fooled the earthlings so that they would land their ship on their planet. That scene is the only part of the movie I remember.

Does anyone have a clue?

Thank you very much.
