Uber-producer Scott Rudin has joined the producing team of Martin Scorsese’s in-development Frank Sinatra biopic. Rudin is coming off a strong, if ultimately disappointing, award season as producer of both True Grit and The Social Network. Scorsese has been working on his Sinatra biopic for a while, and plans to ultimately direct the project when it’s ready. Though one would assume that Leonardo DiCaprio would be Scorsese’s top choice to take on the role of the crooner, the director recently dropped quite a few big names of actors he’d like to work with including Johnny Depp, George Clooney and Brad Pitt.Deadline reports that Phil Alden Robinson (Field of Dreams) originally worked on the script for the flick, but Universal is currently looking for another scribe to take one more crack at it. Hit the jump for more on the project and what’s ahead for Scorsese. [Update: Speaking to MTV, Robert De Niro says that Scorsese will shoot Silence next, then The Irishman with De Niro, Joe Pesci, and Al Pacino. More after the jump]Most recently, Scorsese stated his desire for Al Pacino and Robert De Niro to take on Sinatra and Dean Martin, respectively, in the biopic. The director has been toying with the idea of having different actors play Sinatra at different stages in his life, so this casting makes sense. Though it may be a bit jarring to see different actors take over the Sinatra role in the film every 30 min or so.Scorsese is currently in post-production on his 3D family flick Hugo Cabret, which was recently slated for a Thanksgiving release of November 23rd. Up next, the director may tackle the long-in-the-works 17th century Jesuit priest drama Silence, with Daniel Day-Lewis, Benicio Del Toro and Gael Garcia Bernal possibly starring.  He’s also attached to the adaptation of Jordan Belfort’s 2008 memoir The Wolf of Wall Street, a financial drama with Leonardo DiCaprio set to star. In addition, Scorsese is also planning on making the gangster film The Irishman with Robert De Niro, Al Pacino and Joe Pesci. De Niro keeps promising that the film is definitely happening soon, so this one could also feasibly be Scorsese’s next.[Update: In an interview with MTV, De Niro had this to say regarding whether The Wolf of Wall Street would delay The Irishman: "I think there's one other movie he's going to do called Silence, it's a movie he's always been wanting to do, and he just finished Hugo Cabret, and then we'll do our film." So, there's what Scorsese's slate looks like at the moment. Though until this is confirmed by Scorsese himself, I'd still take it lightly. Things can, and do, change. But it looks like under ideal circumstances, this is how things would pan out.] Rudin won’t have to be licking his wounds for too long following The Social Network’s Best Picture loss, as he has a number of high-profile projects lined up this year. He’s producing David Fincher’s The Girl With the Dragon Tattoo, Stephen Daldry’s currently-in-production adaptation of Extremely Loud and Incredibly Close with Tom Hanks, Sandra Bullock and John Goodman, the Aaron Sorkin/Steven Zaillian-scripted baseball drama Moneyball starring Brad Pitt and Phillip Seymour Hoffman, and Sacha Baron Cohen’s next comedy The Dictator.
