A nice-looking guy, but I dunno... he looks too sweet, too nice to be Brock.
As far as 3 being it, 3 may well *be* it... for Raimi. He'll probably step down after 3. I find it impossible to believe that a franchise this lucrative is going to be allowed to die on the vine: if only to spawn other, new spin-off franchises. The first and most valuable one I can think of would be a Venom series. We want it rated R, we want of course for Spidey to cameo in it, and last but certainly not least we want movie one of course to be Venom's origin, and in the second we'll see Carnage's origin, hence the R-rating. There is no sense doing symbiotes with a PG rating: ask the folks who did Alien vs. Predator how well sticking PG ratings on evil, violent creatures works.
It's also entirely possible Sony might be dumb enough to do a Black Cat spin-off; I could totally see that happening. The failure of WB's Catwoman-In-Name-Only film may have hurt that, though. My feeling is, fine, do one... I do not have to watch it.
Three years is a long time. I'm definitely taking "no more movies after 3" with a grain of salt. Who knows if the exec who said that will even BE at Sony 3 years from now?!
