Warner Bros. has released the first trailer for director Peter Segal’s (The Longest Yard) upcoming comedy Grudge Match. Sylvester Stallone and Robert De Niro star as two retired professional boxers who used to be boxers.  When they end up getting into a fight while filming mo-cap for a boxing video game, an official rematch is planned and the older gentlemen now have to get into shape.  While a boxing movie starring Stallone and De Niro could have easily been a straight drama, this trailer shows that Grudge Match is very much a comedy—complete with a Rocky gag and plenty of “you’re so old that ___” jokes.  There’s also a bit with a creepy CGI’d version of Stallone’s younger self retiring from acting, but overall the chemistry between the two and their trainers (played by Kevin Hart and Alan Arkin) looks fairly promising.

Hit the jump to watch the trailer.  The film also stars Jon Bernthal, Kim Basinger, and Camden GreyGrudge Match opens on Christmas Day.

Here’s the official synopsis for Grudge Match:

In “Grudge Match,” De Niro and Stallone play Billy “The Kid” McDonnen and Henry “Razor” Sharp, 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.
