If you’ve lived your whole life waiting to see a 70-year-old version of the man who played Jake LaMotta duke it out with a 67-year-old version of the dude who was Rocky, this is your moment. Director Peter Segal (Tommy Boy, Get Smart, Nutty Professor II: The Klumps) brought Robert De Niro and Sylvester Stallone together, added some wisecracking Kevin Hart, a little Kim Basinger and Shane from The Walking Dead, and Alan Arkin in a Mickey Goldmill capacity, and now it’s a real live movie set for Dec. 25.
