In the first two Hulk movies and in "The Avengers" Hulk had spoken very little. Here are the only words he spoke:
2003 Hulk: "Puny human, "Take it all"
2008 Hulk: "Leave me alone", "Hulk smash", "Betty"
Ruffalo Hulk: "Puny god"
Some people think Hulk should talk more. Because in the comics, that's always been the case. More words = more personality, so it is said. This is a double-edged sword: On one hand he would have more personality and on the other hand that could reduce his personality. What works in comics does not necessarily work in film. Hulk is a maverick character, he only appears when he is angry (or under enormous stress, pain etc.) and is only doing what he thinks is right. An attempted compromise could lead to a smash. When he talks all the time and tries to discuss everything, then there is the risk that he is no longer taken seriously by the audience. Where he says: "No, I do not want", he might roar or smash something. It is his childlike, defiant behavior and low intelligence that makes him the Hulk. A few words will not change anything, conversations or discussions would.
What do you think? Should Hulk talk more in movies?
