I vaguely remember seeing an old B&W movie on TV, probably late '50s or early '60s, about 2 brothers fighting each other. I think it took place on an apartment building roof or maybe on a longshoremen's dock in NYC. One of the brothers had a hook for a hand, which made him more dangerous - but I think still lost his life at the end. Anyone know the title?

I would say blood in blood out but the guy lost his foot instead of his arm . So CandyMan ? He was jumped by a group of people

No, both of those movies were from the '90s anyway, and the one I remember was from the '50s in Black & White. Anybody else?
