VIDEO : Ahead of Rocky's 40th Anniversary Sylvester Stallone Shares Rare Photos

Rocky IV is truly unique - a third sequel in a long-running franchise that somehow earned a legendary cult-status to rival the acclaim of the original Rocky. It's not like Rocky IV is the best film ever made (far from it, if we're all being honest), but the tale of Rocky Balboa ( Sylvester Stallone) taking on Soviet Union boxing machine Ivan Drago (Dolph Lundgren) has become the stuff that American pride is made of.
