Actors Brendan Fraser and Dominic Purcell are set to fight it out to play The Incredible Hulk's alter-ego Bruce Banner in the movie's sequel following Eric Bana's decision to pull out of the project. Bana played the shape-shifting doctor in the 2003 movie, and was initially interested in a return to the role - if the timing was right.
But, according to website Cinescape.com, the Aussie actor has stepped down as The Hulk medic and now The Mummy star Fraser and Purcell are the favorites to don the white coat and attempt to control their rage.
