Many pot-fueled debates will be settled when Robert De Niro and Sylvester Stallone finally step into the ring in Grudge Match. (Not to be confused with Grunge Match, the Pacific Northwest artisanal match store.) The two men will play old (obviously) boxers, who come out of retirement to fight each other. Kevin Hart will play the promoter who convinces them. Entourage mastermind Doug Ellin wrote the most recent draft, and Peter Segal (Get Smart, Tommy Boy) is attached to direct. Warner Bros. has finally given the project, which has been knocking about since 2010, the go-ahead.
