John Travolta is in the middle of a sit-down with John Gotti's oldest son -- Junior Gotti -- in an effort to get John to sign on to play the "Teflon Don" in a biopic about the mafia icon.
The two sat down with the movie's director Nick Cassavetes and executive producer Marc Fiore.
As TMZ first reported, sources close to the project tell us Travolta is in serious negotiations to play the role, but he hasn't signed the contract yet.
And, as we reported, producers are eyeing James Franco to play Junior Gotti.
Outside Amici restaurant in Brentwood moments ago, Gotti called John a "tremendous actor" -- and said he was "totally confident" that John would nail the part.
