Robert De Niro and Sylvester Stallone are about to put the age old question to rest, "Who would win in a fight, Jake La Motta or Rocky Balboa?" As they team up for the boxing comedy Grudge Match, which finds the Rocky star stepping in the ring with the Raging Bull Oscar winner for one final match in their old age. The first photo has arrived from the set, which finds the two actors beat to a bloody pulp alongside NBA star Robin Lopez. Does this pic get you excited? Or do you think De Niro and Sly should retire from the ring before they really hurt themselves?
