Talking about his dream job to direct any "Batman" movies, helmer Brett Ratner suggested that the first spin-off movie made from the bat-themed superhero series should be about Joker. To MTV News, the man behind "X-Men: The Last Stand" said that exploring Joker's origin as the Red Hood would be "really cool".

Emphasizing on how grand Joker is as a villain, the 39-year-old filmmaker suggested that there are other actors, who can interpret the psycho as great as Jack Nicholson in "Batman" and Heath Ledger in "The Dark Knight", putting Robert Downey Jr. name as one of them. Ratner explained. "...Joker is a great villain. That's why Jack Nicholson and Heath Ledger had so much to work with. And I think there will be another actor who can interpret that. It would be great to see [Robert] Downey [Jr.] as the Joker, for instance."

Following the massive success of "Dark Knight" on retaining the second slot of highest grossing movie of all time with $522.1 million nationwide since its release on July 18, the superhero franchise has been hit with many speculations over its possible sequel, "The Caped Crusade". But, the idea for Joker spin-off has yet to be suggested until this Ratner's remark came out.

Concerning "Dark Knight" sequel itself, it is said to have villains from The Riddler to Catwoman with the casting rumors linking actors like Johnny Depp, Philip Seymour Hoffman, Cher and Angelina Jolie. But, both Depp and Hoffman have denied their knowledge on the possibility of them playing The Riddler or Penguin.
