Marvel Comics and ABC are in the early stages of planning such a thing, according to reports. The Hulk also will figure in the upcoming Avengers movie, so we may be seeing his big, green face everywhere.
I can see the Hulk working well on TV. After all, he's already had one long-running live-action series. The small, not the big, screen may be a better venue for him. Following Bruce (or David, I suppose) Banner's struggle to contain his destructive alter-ego week after week can make for good serial drama.
