The bad and the good, three years apart

Rico says he stumbled across The Secret Invasion by accident, and thought he'd give it a try. The fact that it was made by the Corman brothers was a bad sign, but surely worth a look.
Well, not really, but you'd think, with Stewart Granger and Henry Silva, how bad could it be?
The answer is, with Raf Vallone (did he ever make a good movie? Yes, as it turns out, with thanks to IMDB: The Italian Job, with Michael Caine), Mickey Rooney, and Edd Byrnes (yes, he of 77 Sunset Strip), really really bad...
The Dirty Dozen, made three years later, was so much better.
