Looking for an old martial arts movie. I think its meant to be a bruce lee look alike. I don't remember much but I do remember the ending. The bruce lee look alike has to have final fight on a roof top with the bad guy the bad guy is wearing shoes with spikes on the bottom and cuts the bruce lee look alike on various parts of his body. Finally the bruce lee look alike deliveries a deadly punch to the bad guys and rips out his heart, the heart is still beating in his hand and the movie ends after that. Any suggestions please
