SHH scooper 'TheBeastWithin' says that the latest issue of Maxim magazine has an article on The Hulk and Marvel Studios' Avi Arad was asked whether the green fella talks in the movie...
"But what we want to know is, will we be hearing "Hulk Smash"? "He's not going to speak, really. Only a couple of words, maybe," (Avi) Arad chuckles. "Like a baby. But you're in the neighborhood with 'Hulk Smash!'"
And that is good news.
