If the sight of Leo in Revolutionary Road is any indication--the period fedoras, the stream of martinis, the Sinatra-esque, slicked-back hair--we think he'll (potentially) do just fine. Depending on his pipes.

Whence this speculation? From the news this morning that Oscar-winning director Martin Scorsese will helm a long-anticipated biopic of the singer, to be backed by Mandalay and Universal Pictures. (If you haven't seen the last four Scorsese films, the connect-the-dots point here is that DiCaprio has starred in all of them--Gangs of New York, The Aviator, The Departed and this October's Shutter Island all tally DiCaprio as a lead).

Amazingly, this is the first bigscreen picture to tackle Sinatra's life. Our blind faith in the Marty-and-Leo tag team has us pumped (should the latter land the gig) -- but what do you think?
