Leterrier on Abomination

“Obviously, General Ross is the villain, so he had to be in it,” added
Leterrier. “But the Abomination, Emil Blonsky, was who Marvel wanted to put in
this chapter—the first chapter of our new saga—because he’s the most famous.
He’s an enemy that can actually threaten the Hulk. It’s very important for me
that there is a danger. When Bruce Banner is Hulk, I didn’t feel in Ang Lee’s
‘Hulk’ that there was any threat. He was invincible. So with Abomination there’s
actually a monster that can, you know, kill him when he’s in the Hulk form.”

Good, true to the source material and what I’ve always liked about The Hulk mythos is that EVERYONE is out to get him.
