Frank has a big head. Not in an egotistical way, but in an actual big head way. Well, not an actual head, but a giant papier-mâché head that he wears over his real head (which he refuses to let anyone see). Sounds weird, right? Well it is, but strangely enough, it is also kind of endearing.
As one of the film’s characters explains early on, “Frank, even with all his issues, is without a doubt, 100% the sanest cat I’ve ever met.” He continues, “Look, you’re just gonna have to have to go with this.” Of course, this advice comes from a guy with a serious fetish for mannequins, but that’s just the kind of film Frank is, and as an audience, we are just gonna have to go with it.
