This film likely ranks as DeForest Kelly's most notable non-Star Trek feature film, where he played a college administrator opposite a rancher played by Rory Calhoun (you know, the person who's always standing and walking). In an attempt to combat an infestation, they try hormone therapy, but after a little girl switches the experimental and control subjects (this isn't a social science experiment ... real scientists actually need those!), the experimental test subject escapes creating what might be the cuddliest giant kaiju in film history. Identify this 1972 film about menacing, giant rabbits.
