If you are old enough, you probably remember this as a series in the late 60s or early 70s. There were two versions of the series pilot. One aired as a TV movie and the other was released as a feature film. Bonnie was topless in the theatrical version.
I remember the title, although I never saw either the TV show or the movie. The title confused me, because I thought it had something to do with Charles Bronson, but it seemed odd that they would use his real name. But there was a lot of weird stuff going on then, so who knew?
