Hulk and Thor were initially not enlisted to appear in the upcoming movie. However, the "Ironman" actor has informed Ruffalo about his presence as Hulk, reported Aceshowbiz.
"If Robert Downey Jr says I am in 'Captain America' , I am in 'Captain America'... And I will wait for the day that my call sheet shows up on my doorstep or my script," Ruffalo said in an interview with HitFix.
The 47-year-old actor also said that he had not been contacted by anyone from the production as of yet. "At this point, I am told that I am in it by Robert, which I will take as biblical, but I just have not heard or seen from production yet."
