Sylvester Stallone, Robert De Niro Team For 'Grudge Match'?

Sylvester Stallone. Robert De Niro. Fight?

TheWrap reports that Stallone and De Niro could join forces for "Grudge Match," a long-gestating comedy about two retired boxing rivals who step back into the ring one last time. The site notes that while the project doesn't have a green light just yet, Warner Bros. is looking to shoot "Grudge Match" in early in 2013.

Or maybe not. Back in 2010, Stallone and De Niro were first attached to "Grudge Match," but that iteration never got off the ground.

This is a busy time for De Niro, who has taken to playing up his advancing age in recent projects: He's attached to star in "Last Vegas," an AARP-version of "The Hangover," with Michael Douglas, and has long discussed reuniting with Martin Scorsese for "The Irishman," about an aging mobster. Stallone, too, has had his fare share of age-appropriate victory laps: "Rocky Balboa," "Rambo" and "The Expendables" and its sequel, which is due out this summer.
