Warner Bros. Pictures has released the teaser trailer of “Grudge Match” starring Sylvester Stallone and Robert De Niro as old boxing rivals who come out of retirement for one final match.

In “Grudge Match,” Stallone and De Niro play Henry “Razor” Sharp and Billy “The Kid” McDonnen, two local Pittsburgh fighters whose fierce rivalry put them in the national spotlight. Each had scored a victory against the other during their heyday, but in 1983, on the eve of their decisive third match, Razor suddenly announced his retirement, refusing to explain why but effectively delivering a knock-out punch to both their careers. Thirty years later, boxing promoter Dante Slate Jr., seeing big dollar signs, makes them an offer they can’t refuse: to re-enter the ring and settle the score once and for all.

But they may not have to wait that long: on their first encounter in decades, their long-festering feud erupts into an unintentionally hilarious melee that instantly goes viral. The sudden social media frenzy transforms their local grudge match into a must-see HBO event. Now, if they can just survive the training, they may actually live to fight again.

The film also stars Kevin Hart as Dante Slate Jr.; Alan Arkin as Razor’s former trainer, Louis “Lightning” Conlon, who gets to put Razor through his paces again; and Kim Basinger as Sally Rose, who was once the love of Razor’s life.

Peter Segal is directing from a screenplay by Rodney Rothman, story by Tim Kelleher.

Opening across the Philippines in January 2014, “Grudge Match” will be distributed by Warner Bros. Pictures, a Warner Bros. Entertainment Company.
