Fan Casting Batman & Superman: World's Finest Trilogy

In a trilogy of movies, we see the big lead up to Batman and Superman's first time meeting. In Batman's film, he's well into his years of fighting crime and more specifically, the Joker. During Joker's latest plan, Batman feels he needs help, so he calls in his old sidekick, Dick Grayson, and Commissioner Gordon's daughter, Barbara Gordon, to help him fight the evil clown. In Superman's film, he finds himself battling Lex Luthor and trying to prove that he is selling weapons to terrorists. All the while learning about Batman and what he's like. These movies culminate in World's Finest when Bruce Wayne goes to Gotham City for a press tour for his latest book, "Orphaned Billionaire: How I Coped With Loss." The Joker follows closely behind him, intent on teaming up with Lex Luthor to defeat both Batman and Superman. With their alliance made, Batman and Superman, despite their strong disliking of each other, must team up to stop the mad clown and corrupt businessman. The end of the final movie in the trilogy foreshadows a future Justice League movie with Brainiac as the main villain.
