'Avengers' star Ruffalo has had Hulk rage moments Associated Press Copyright 2012 Associated Press. All rights reserved. This material may not be published, broadcast, rewritten or redistributed. Updated 06:45 a.m., Thursday, May 3, 2012 Ruffalo, who comes off as a guy that could give Clark Kent a serious challenge in the mild-mannered department, plays brilliant scientist Bruce Banner — and his big, green, mad-as-hell alter-ego, the Hulk — in the superhero tale "The Avengers," opening Friday. "When I was a young actor, if you came to my apartment, you would have seen pictures and photos hung in the most bizarre places, where they were covering holes in the wall from auditions that I didn't get or slights that I felt I had suffered, where things were thrown, cups were thrown at the walls," Ruffalo said. An Academy Awards nominee for 2010's "The Kids Are All Right," the 44-year-old Ruffalo has, in characteristically unassuming manner, built an impressive list of credits in independent and studio films, including "You Can Count on Me," ''Shutter Island," ''Zodiac," and "Eternal Sunshine of the Spotless Mind." [...] through motion-capture technology in which Ruffalo's body language and performance is digitally captured as the undercarriage for the Hulk, topped off by computer animation, the green giant looks more genuine and moves more credibly among real people than he did in the earlier movies. The Hulk's face even resembles Ruffalo's — tinted green and strained and bloated in colossal rage. With the foundation Ruffalo has built in "The Avengers," Whedon said he would love to see him in a solo Hulk movie.
