Never saw Hasseloff's version. But the Nick Fury I know is a tough as nails military man turned superspy. That's who Jackson plays. So far I haven't seen enough background for Jackson's Fury to go beyond that. "White" Fury in the comics grew up poor and on the streets. He joined the military and went from enlisted man to officer eventually heading an international espionage organization. Seems to me that could be part of the background for Jackson's Fury as well. But I don't know if that's true because it hasn't been explored. Being a fan of comics, I think Jackson's take on Fury is probably influenced by "White" Fury.
