Marvel or whatever company that did the Avengers signed Mark Ruffalo to do six Hulk-containing films. SIX. After hearing that, I wouldn't doubt if FOX signed Noomi and Michael to do at least one sequel. I know The Avengers made a shit more money, but still...Prometheus did pretty damn good for an R rated film, in this day and age, with PG-13 competition like Madagascar, Brave, TASM, etc...
