Powerful, resentful and diabolically clever hypnotist Carlo Lombardi (deliciously played with lip-smacking suave menace by Chester Morris) puts his beautiful lady assistant Andrea (the strikingly lovely Marla English) under his evil spell and causes her to transform into a hideously ugly, scaly, clawed murderous prehistoric she beast (famed 50's monster make-up maven Paul Blaisdell in a fabulously funky rubber suit) which bumps off people he hates. Moreover, Lombardi joins forces with equally amoral greedy rick jerk Timothy Chappel (a nicely wicked portrayal by Tom Conway) so he can achieve fame and fortune predicting the next killing. Boy, is this one enjoyably cruddy low-budget 50's creature feature schlock horror hoot! It's got all the usual bad film vices (or are they virtues?) which make this kind of dross so entertainingly awful: blah direction, incredibly slow pacing, chintzy cinematography, some very poor acting (Lance Fuller as Lombardi's rival gives a performance that's so flat and wooden you can use it as a diving board), a hokey script, a seedy seaside California location, blundering idiot cops, lousy dialogue, a laughably sluggish'n'shambling monster that's more silly than scary, and a rousing cornball spacey'n'spooky score. A bit dull and talky in spots, but overall still loads of delectably cheesy B-horror fun.
