I watched one of the old TV movies based on the show just yesterday. It was a good show, though some episodes were better than others.
I have a feeling the Hulk would be computer generated and not a real person. Putting a guy in green body paint and a wig worked okay for the original series, but it wouldn't be as well accepted by today's audiences. We're too spoiled by special effects.
Ferrigno has provided voice work for some recent versions of Hulk, like the last movie and an upcoming Avengers cartoon. He might be recruited to do that again if the series does use a CGI Hulk. I don't know who they'd get for Banner. Maybe the guy who will play him in the Avengers movie? That would be some great cross promotion for Marvel's movies and TV shows.
