'Sweeney Todd' star Johnny Depp is being tipped to play The Riddler in the next Batman sequel.
Following the huge box office success of the Christopher Nolan- directed 'The Dark Knight', producers are hoping that they can convince Depp to take the role.
The National Enquirer also reports that studio bosses are hopeful that Oscar winner Philip Seymour Hoffman will take on the role of The Penguin.
Earlier this week it was reported that Angelina Jolie was interested in taking the role of Catwoman in any planned sequel to 'The Dark Knight', which has grossed over €280m worldwide.
The Riddler was last played on the big screen in 1995's 'Batman Forever' by Jim Carrey, while Danny DeVito was the last actor to play The Penguin in 1992's 'Batman Returns'.
A source told the National Enquirer: "(Producers) are convinced that the role of the Riddler is perfect for Depp. Johnny's a pro.
"He'll be able to take direction from director Chris Nolan and still make the character his own. And what better Penguin is there than Philip Seymour Hoffman."
