The Creeping Flesh (1973)
Not as good as I remember - pretty muddling plot about a scientist played by Peter Cushing who finds the missing link in the form of a giant skeleton that can regenerate. Meanwhile is wife dies in an Insane Asylum run by Chris Lee and it looks like his daughter is going to end up barking mad too. Not a Hammer film despite the cast (Michael Ripper is there too) and time frame.
