A few years ago, Sandy Collora released a fan film called World's Finest, a fan-made trailer for the fictional movie. Unlike "lame" fan trailers, this one used real actors with newly shot scenes for the trailer.

This World's Finest trailer is quite average, not nearly as polished or compelling as Sandy's first fan-made Batman: Dead End, and not nearly as fun as John Fiorella's fan trailer, Grayson. In many respects, World's Finest isn't very good at all... but it's the closest thing we'll ever get to a live action version.

According to Wikipedia:
"World's Finest is a fan film directed by Sandy Collora. It works as a trailer to a movie that does not exist: the long-awaited cinematic team-up of Superman and Batman. While Superman and Batman have appeared together often in comic books and in animation (notably Super Friends), this fan film is the only time that the characters have been on the screen at the same time in live action... this film was intended as an audition reel, showing his directorial talents."

Let's take a look at World's Finest now!
