Jennifer Connelly says she found filming some scenes for The Hulk "humiliating".

Connelly plays Betty Ross in the film which stars Eric Bana as Bruce Banner/The Hulk and is being directed by Ang Lee.

When she first begin working on the movie Connelly had to act opposite a cardboard head doubling as The Hulk, which will be created using computers.
The cardboard head isused to give Connelly her 'eye lines'. "I'm looking at pieces of pink tape on the cutout head," she tells Vainty Fair. "There's nothing there! I've never done that before, it's a little humiliating."

Lee told the magazine: "The first day it was a bit of a problem having her talk to the Hulk head".
"But within a week, she had a scene with the Hulk where she looks at him with real feeling, and all the emotion was there."
