Scorsese planning a Sinatra biopic?

In a recent interview, Martin Scorsese discussed his plans for a future Sinatro biopic, saying that the style of the project would likely fall somewhere in between Goodfellas and The Aviator.

... in structure I’d like it to be more like GoodFellas. But like The Aviator, it only deals with certain times in his life. We can’t go through the greatest hits of Sinatra’s life. We tried this already. Just can’t do it. So the other way to go is to have three or four different Sinatras. Younger. Older. Middle-aged. Very old. You cut back and forth in time – and you do it through the music. See what I’m saying? So that’s what we’re trying for. It’s very tricky [laughs].

This sounds like it could be quite the success in my opinion. There hasn't really been a great movie made about Sinatra yet. When The Rat Pack was on HBO, I thought someone might run with it, but to date all attempts to make a movie apparently never saw the light of day. I'm not sure that this one is through enough of the pre-production process to call it a done deal, but the planning is definitely moving along.

So what does Scorsese say about who will play Ol' Blue Eyes:

Johnny Depp is one, I like him. He's unique. I don't know how he does it. George Clooney. Brad Pitt's interesting. And Tobey Maguire. There's a lot of good people. 

I'm also wondering a couple other things, like how far are they going into Sinatra's personal life, or will it mainly focus on him as a musician? And if it does, will they let whoever they get to play him sing a la Kevin Spacey in Beyond the Sea? Or is it going to be lip-synced?

Tentative release date is sometime in 2011, so there's plenty of time for this stuff to be figured out. We'll update as people are attached, especially to the lead role, mainly because I'm curious.
