A curious thing happened today, a friend described a movie scene and for the life of me I don't recall it and I can't figure out what it is. Had to do with a brother returning home after mother passes away. Discovers a cave under house and finds brother has been turned into a spider and is living in the cave. She said she thought it was around the same time as Omega Man. Any help is appreciated! Not a lot to go on but hope someone will recognize it!
