Jon Bernthal signs on to star in <i>Grudge Match</i>Jon Bernthal, best known for playing Shane in the first two seasons of The Walking Dead, has signed on to star in the Warner Bros. boxing comedy Grudge Match.

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.

Jon Bernthal will next be seen in Ric Roman Waugh's Snitch and Martin Scorsese's The Wolf of Wall Street.
