Re: Howard says that not getting to Reprise his Ironman role killed his career!
In a way I'm kind of glad about both Howard and Norton getting the axe. Marvel needed to pretty much make it clear that NOBODY is absolutely indispensable so that they can discourage opportunistic actors/directors/writers from trying to use their clout to hold Marvel up for more money. I'm sure Marvel wants talent and is willing to pay for it but I don't think they're willing to get taken advantage of.
There's no such thing as a movie that's too big to fail.
