Monster on the Campus (1958) d. Arnold, Jack (USA)

While experimenting with a prehistoric fish, mild-mannered university professor Arthur Franz inadvertently learns that contact with the creature’s gamma-radiated fluids has numerous unfortunate side effects, resulting in savage German Shepherds, oversized mosquitoes and murderous Neanderthals. What’s not to like?

Often cited as a big black mark on sci-fi veteran Arnold’s resume, this sci-fi twist on the Jekyll/Hyde-lycanthropy tale turns out to be much more entertaining than it has any right to be. The biggest hindrances here are the rushed, attempt-at-pathos ending and Joanna Moore’s one-note performance as Franz’s girlfriend – until she starts getting carried off by prehistoric paramours, that is. Then the screams flow like Paleolithic waters.

Fun stuff, and it’s got Troy Donahue.
