Winner: "All About Steve"

This actually happened. Somebody actually decided to take the name of the gay porn version of a Bette Davis classic and use it as the title for a romantic comedy, and nobody stopped them. This seems like the working title somebody put on the front page as a joke, and by the time anybody noticed the horrific pun, they'd already printed 10,000 posters and didn't want to waste the money to change it.
