Is the director of “Happy Feet” considering working with Superman, Batman, Wonder Woman, The Flash and Green Lantern on his next project? That is the latest rumor to emerge from the internet. After “Happy Feet” proved to be a $380 million dollar box office hit worldwide, movie studio Warner Bros. has likely elevated the film’s director, George Miller, to the top of its standings. Two entertainment websites have reported that Miller is now the front-runner to helm a “Justice League of America” movie that would see five of DC Comics best-known heroes join forces, a feat that hasn’t happened yet on the big screen. Warner Bros. released “Superman Returns” last year and is planning on releasing the second Batman movie that will star Christian Bale next summer so already audiences are familiar with two young actors playing the Man of Steel and the Dark Knight. Work on live-action “Wonder Woman” and “Flash” movies has never quite gotten off the ground so a five hero movie may be the perfect opportunity to launch new superhero movie franchises for the studio. Supposedly Warner Bros. is more eager to make a “Justice League” movie first than a sequel to “Superman Returns”.

A screenplay is being written for the “Justice League” film and if Miller agrees to do it filming wouldn’t be able to start until after Christian Bale completes his duties on “The Dark Knight” later this year. Additionally the budget for making all of these heroes fly and fight on-screen would likely propel the movie’s budget upwards of $200 million dollars.

Work continues to take place on “The Dark Knight”, the follow-up to 2005’s “Batman Begins”. Director Christopher Nolan will be behind the camera once again, this time working from a screenplay written by himself and his brother Jonathan. Christian Bale is reprising his role as billionaire Bruce Wayne and costumed crime-fighter Batman, the vigilante protector of Gotham City. Also returning are Michael Caine as Wayne’s butler and confidant, Alfred; Gary Oldman as crusading cop James Gordon and Morgan Freeman as Lucius Fox, the developer of Batman’s arsenal of weapons and vehicles.

Three new cast members are joining the movie. Heath Ledger, the hunky star of “A Knight’s Tale”, has already been cast to play Batman’s arch-nemesis, The Joker. Close to signing a contract is Aaron Eckhart (”Thank You for Smoking”) in the role of Two-Face, the scarred villain that bases all of his decisions on the flip of a coin. Finally, Maggie Gyllenhaal (”World Trade Center”) is rumored to also be close to joining the cast to take over the character of Rachel Dawes, the love interest for Bruce Wayne. Katie Holmes played the character in the earlier film.

Filming on “The Dark Knight” commences next month in Chicago and you will be able to see the movie in theaters in the summer of 2008.
