I am Iron Man, the Great and Powerful!

According to First Showing, Robert Downey Jr. might star in an upcoming Sam Mendes movie titled Oz The Great And Powerful. Mendes was originally going to do the next James Bond film, although that's been put on hiatus because of MGM's financial problems. This new project was first slated under the title Brick which was written by Mitchell Kapner who did The Whole Nine Yards, and is being produced by Joe Roth. Downey has been offered the role of the Wizard, which in this movie is supposed to be a prequal to the original Wizard Of Oz story that tells of the title character's life prior to coming to Oz and how he became the "man behind the curtain".
