With every new name that comes on board, the much-talked-about John Gotti biopic 'Gotti: Three Generations' sounds more and more legit, and the most recent news surrounding the flick comes straight from the very top of Hollywood's A-list: Al Pacino has joined the project as Gambino crime family underboss Neil Dellacroce.

Pacino starred in arguably the best and most well-known mob movies of all time, the 'Godfather' trilogy, so his addition to the project brings with it a certain gravitas. Indeed, the entire project has gotten a highbrow facelift recently; in addition to Pacino, it was announced last week that six-time Oscar nominee (and Best Director winner for 'Rain Man') Barry Levinson would direct the film, and that he and his award-winning 'Bugsy' screenwriter James Toback would rewrite the script.
