Mark Ruffalo as Bruce Banner / Hulk: A genius scientist who, because of exposure to gamma radiation, transforms into a monster when enraged or agitated. Ruffalo, who was considered to play Banner in The Incredible Hulk before Edward Norton took the role, was cast after negotiations between Marvel and Norton broke down. 關於取代Norton,Ruffalo話",我係艾德嘅朋友,係,呢個唔係好辦法.但我覺得艾德遺留咗呢個角色畀我. 我將佢睇成我呢一代嘅哈姆雷特". 關於角色,佢話",佢係一個同自己兩面<unk>扎嘅男仔,而且佢喺佢人生嘅每件事都完全可以控制. 我喺漫威同諾頓之前就曾經考慮過喺The Incredible Hulk扮演嘅布魯斯·魯法洛. 佢係喺漫威/諾頓之前扮演嘅布魯斯·哈姆雷德嘅角色. 佢喺漫威電影嘅角色扮演過. 我諗到佢會令其他男人嘅面孔變得好似黑龍漢嘅".
