DiCaprio, Clooney, Depp fight for 'Sinatra'

Leonardo DiCaprio, George Clooney and Johnny Depp are allegedly being touted for the lead role in Martin Scorsese's Sinatra.

According to the New York Post, the makers of the high-profile biopic are struggling to agree on which A-lister to cast as legendary Rat Pack crooner Frank Sinatra in the Phil Alden Robinson-scripted project.

Director Scorsese reportedly wants his Departed star DiCaprio in the lead role, while executive producer Tina Sinatra is keen for George Clooney to portray her father. Studio Universal, meanwhile, is eager to cast Johnny Depp in the coveted part.

"Marty wants it to be hard-hitting and showcase the violent, sexually charged, hard-drinking Frank, but Tina wants to show the softer side of her dad and let the focus be on the music," a source said.

"The '60s were a very swinging time for Frank - he was having sex with a garden variety of bimbos and cementing his Rat Pack status. It's a really key time to his mythology. And Tina really wants to make sure that a sanitised Frank comes through, and that it's not overly negative."

Scorsese is expected to turn his attention to the Sinatra film after the release of Shutter Island.
