The filmmaker told MTV that the ABC adaptation will draw its influence from Marvel comic books and follow its own continuity.
"We had a long, long talk about that, and we've been given license," he said. "I mean, I think the comics, y'know [...] Pak's Hulk is great, and Loeb's Hulk is great, and there's so many things in the Hulk universe that are powerful strands of narrative. They know we are being faithful to those strands, and the movies have their own continuity."
del Toro went on to say that accommodating Hulk with a TV effects budget has been a challenge. "We are finding ways around it. It's a tricky one to figure out in the model, but if we are successful at that, then you can go into it," he added.
ABC president Paul Lee previously announced that he expects Hulk and fellow Marvel project AKA Jessica Jones to be part of its next pilot season. Cloak & Dagger and Mockingbird series are also in the pipeline at the network.
Incredible Hulk is expected to air in 2012.
