BEFORE I EVEN BEGIN my review, let me preface it by saying there’s no way I can avoid the occasional use of explicit sexual language that may make some readers uncomfortable or upset. “Auto Focus” is, after all, about Bob Crane, and it doesn’t exactly focus on the man’s acting career, but rather on some of his more bizarre sexual habits. At this point, if you’re still wondering who Bob Crane is and why you should care, there’s probably no need for you to read on. On the other hand, if you’re fascinated by the strange life and bizarre death of the leading man from “Hogan’s Heroes,” you’re in the right place.

Now that we’re no longer in mixed company, let’s begin. Why are people fascinated by Bob Crane? He made his name off of one quirky sitcom and tried to trade off of it long after the show was cancelled. And as for his sexual proclivities, they aren’t too unheard of, considering the activities of other public personalities–some rumored to involve gerbils or dressing in women’s lingerie and taking a bite out of their partners’ backs. In terms of multiple lovers, Crane’s list is nothing compared with Gene Simmons’s and Wilt Chamberlain’s, and nobody has made a serious movie about either of them.
