O Monstro Sanguinário

A college professor obtains an ancient life-form whose fluids soon turn deadly.

Looks like Universal just couldn't give up their werewolf franchise. So they reworked it, replacing full moons with prehistoric "coelacanth" fluid. Seems the stuff turns modern creatures into vicious prehistoric counterparts. So a sophisticated modern guy like Prof. Blake (Franz) turns into a hairy, monstrous hominid, and Hollywood 1958 scares drive-in kids the way necking teens hoped.

You gotta give actor Franz credit. He treats the drive-in material like it was Ben Hur. There's not a hint of camp in the sometimes campy material. But then it's got not only studio backing, but ace sci-fi director Jack Arnold ( e.g. The Incredible Shrinking Man {1957}) at the helm. So the camera never falters even when the cardboard monsters do. (Please, couldn't they have re-worked that awful dragonfly.) Thus, the results suggest eye-level Hollywood professionalism at its most challenged. All in all, it looks like the studio was aiming for respectable sci-fi on the order of Arnold's previous It Came From Outer Space (1953). In my view, Universal only half succeeds, no thanks to the generally poor special effects. Anyway, give actor Franz a combat Oscar for pressing on fearlessly under adverse circumstances. And give director Arnold a Lifetime Achievement Award for excelling in a genre generally bypassed by snooty media critics.

(If memory serves, the coelacanth talked about in the movie was a "missing link" first discovered in the 1930's. Its fish-like body crucially contained fleshy fins, indicating it could move about on land, thus confirming scientific hypothesis that life evolved from the sea.)
