Curse of Bigfoot

Beware - not of bigfoot, but of this movie! It's all about some high school kids who go exploring in a cave and stumble upon a mummy. When they remove it, the nasty old thing comes to life and starts terrorizing their small California town. If this doesn't look exactly like a 1970s movie, that's because producer/director Dave Flocker shot most of it in 1958 as Teenagers Battle the Thing.
