The story centers on two retired boxers (Robert De Niro and Sylvester Stallone) who step back into the ring to settle an old score. Jon Bernthal will play the estranged son of Robert De Niro's character, who feels conflicted about training his father. Kevin Hart, Kim Basinger, and Alan Arkin have also signed on to star.
Peter Segal is directing from a screenplay by Tim Kelleher, which was recently rewritten by Entourage creator Doug Ellin. Bill Gerber, Michael Ewing, and Mark Steven Johnson are producing. Shooting is scheduled to begin next year in Louisiana.
