Things this stole from Rocky
1. Opening the film in some dirty, wild boxing venue, showing our protagonist in a brutal pugilistic display in which there's no sense of victory. Crowd throwing stuff, just as wild as whats happening in the ring.
2. The protagonist yelling out his window at his neighbors, as a means of communication.
3. Scene at home where wifey is trying to get some action, but protagonist must turn her down, so that he can stay tough for the fight
4. Over the shoulder boxing shots.
5. Coincidentals: Both guys are Italian. Both guys have organized crime connections.
