Actually the ratings on Death of the Hulk were so low that Revenge of the Hulk was cancelled and never developed, not because of Bixby's health which was still fine at the time.
Was Revenge the one that was supposed to co-star Iron Man? I thought they planned to bring him to live action.
Wasn't Bixby also involved in the first She-Hulk effort? Bridgette Neilsen's was the second iteration I think, but there was supposed to be a TV show or TV movie with Bixby making an appearance and/or producing or something.
