The film pits Stallone against Robert De Niro, who plays a longtime boxing rival. The pair last fought 30 years ago – and only duked it out twice, each winning one match. After suiting up for some motion-capture for a videogame, the aging boxers get into a brawl and footage of the bout sparks a public demand for a third match between the two to determine who really was the greatest.

The Warner Bros. film from director Peter Segal hits theaters Christmas Day.
