Sylvester Stallone and Robert De Niro have both managed to find a way to put their boxing gloves back on, without reprising their iconic roles from Rocky and Raging Bull. The Hollywood legends star in the upcoming comedy Grudge Match, where they play a pair of retired boxers who are coaxed into the ring one last time to settle an old score. While we have yet to see the stars in the boxing ring, the latest photo shows them getting ready for their big fight, alongside co-stars Kevin Hart, Alan Arkin and Jon Bernthal. Check out this photo from director Peter Segal's comedy, in theaters Christmas Day.
