We can probably consider this the last word on a Planet Hulk movie, at least for the next few years.
Joss Whedon, speaking to IGN at the Much Ado About Nothing junket, was asked about the rumours, and simply said:
Well, I’m really not supposed to comment on it but no, that’s nonsense.
Watch him say that, and only that, in the middle of this pseudo newscast. It’s very MTV.
And now there’s nothing to add. That’s it. End of. Goodnight Planet Hulk.
