Trog (1970)

Anthropologist Dr. Brockton unearths a primitive troglodyte — an Ice Age “missing link”: half-caveman, half-ape — in a local cave. Through medical experimentation, she manages to communicate with him and domesticate him before he’s let loose by an irate land developer and goes on a rampage, terrorizing the local citizenry.
