Last week we told you that Martin Scorsese had signed on to direct an upcoming biopic based on the life of singing legend Frank Sinatra. It appears that Leonardo DiCaprio has the inside track at playing the Rat Pack legend.

DiCaprio has hired a vocal coach as he will be expected to sing all the parts in the upcoming movie. With the aid of a high priced expert telling him how to hit the notes (coupled with high technology) it shouldn't be a problem for him to bag the role.
