I fell in love with this film the first time I saw it on TV and thought, how cool is that, killer bunnies!!! Or. When good bunnies go bad and attack horses, people, cattle, buildings............ I quite felt sorry for them when Rory Calhoun, DeForest Kelley, Paul Fix, Stuart Whitman, and Janet Leigh tried to exterminate the poor things. Particularly when it was their fault to begin with that the poor bunnies ended up HUGE and unremorsefully belligerent. I especially blame that rotten little girl for exchanging the test rabbits so she can keep one as a pet, the one injected with a serum that can cause birth defects, the one that gets away and lives to build its own guerrilla army of vengeful killer bunnies!!! Those poor, much maligned bunnies were transported to the lab of Mr. & Mrs. Mad Scientist in garbage cans for pity sake!!! Did PETA know about this?
The plot was lifted from Russell Braddon's 1964 Sci-fi novel The Year of the Angry Rabbit. The producer (A.C. Lyles) and director (William F. Claxton) were better known for making westerns, hence the proliferation of western actors in the lead roles. It's painfully obvious that everyone was out of their element. I suppose from Claxton's point of view, if he was going to be embarrassed he wasn't going down alone! He took everyone with him, all aboard the crazy train; we're about to crash big time.
In some alternate universe this is a masterpiece of filmmaking. It is beyond bad. The fact that they were all so deadly earnest makes this even more endearing. A stampede of bunnies is not to be missed. I count myself blessed to own a copy of this fabulous crap-fest. Just the thought of it makes me smile.
