Hi there This is my first post on the HTF, so please bear with me. I am looking to name a particular movie that I once saw on television about twenty years ago. It is a science fiction movie about a team of astronauts who land on a planet to investigate the disappearance of a team of researchers (or so I believe). They are attacked by vicious killer rocks - and eaten as well. That is just about all I remember of the plot. But if you can help me, please let me know. Thanks for your time!
