Fantasy like Harry Potter, Highlander and Lord of the Rings is not SF. 2. Super hero stuff like Superman or Spiderman is not SF. 3. Monster films unless solidly built around science is not - King Kong or Godzilla are not. Predator and Terminator are. 4. If you have a film that might be in the gray area for rules 1-3, make a case for it.
Well, if we aren’t counting Samuel L Jackson’s work in UNBREAKABLE and THE INCREDIBLES before tying IRON MAN and CAPTAIN AMERICA into THE AVENGERS, then he’s still the bad-ass Jedi Master with a purple lightsaber about to hit the big screen in the upcoming ROBOCOP movie – with bonus points for JURASSIC PARK.
Heck, if Hugh Jackman hadn’t been so busy playing Wolverine in X-MEN and X2 and X-MEN: THE LAST STAND and X-MEN: FIRST CLASS and X-MEN: DAYS OF FUTURE PAST and X-MEN ORIGINS: WOLVERINE – and, well, THE WOLVERINE – he could’ve done more than just REAL STEEL and THE PRESTIGE and THE FOUNTAIN (and, technically, VAN HELSING and KATE & LEOPOLD).
