Believe this movie was in the 1960s. The one scene I vaguely remember is a group of people walking through a cave and some creature has arms or possibly tentacles 4 on each side coming out of the rock wall that expand and retract. The people synchronize the movement of the creatures arms and each one passes through it so that the tentacles or arms don’t grab them. I’m curious if anyone remembers this movie and what the title is? Thanks so much.
