Only a few days away from The Dark Knight Rises, just enough time to squeeze in a couple more Batman fan films. World's Finest is a fan film created in 2004 by Sandy Collora (see Batman: Dead End). Like the fan film Grayson, World's Finest is a trailer to a movie that does not exist. This format works well for fan films, allowing directors with little to no budget to pay homage to the characters in the span of a few minutes. The ambiguity of the trailer format leaves the viewer to use their imagination to fill in the gaps, which is something most comic book readers are used to.
