They’re both living legends in their own right, and Sylvester Stallone and Robert De Niro have struck gold with their new flick “Grudge Match.”

In a just-released teaser trailer, the “Rocky” hunk and the “Meet the Parents” star play aging, retired rival fighters who cross paths decades after their last fight.

And after a brief fracas, they end up on the road to a historic rematch that’s been thirty years in the making.

Also starring Kevin Hart, Kim Basinger, and Alan Arkin, “Grudge Match” is slated to hit theaters on Christmas Day (December 25th).
