Re: What other Iron Man villains should appear in a sequel
Dreadknight? Hmm, I guess they could revamp him. However I doubt they will do so in the next movie. Iron Man has plenty of other villains who would be far easier to adapt w/o needing a major overhaul(Mandarin, Ghost, Madame Masque, Spymaster, etc.). But if they ever do put him in an iron Man film,he'll definitely need a Whiplash-level make-over. But I think I'd rather save him for when Marvel/Disney gets the rights back to Dr. Doom so they can at least keep that the same as the comics.
There's no such thing as a movie that's too big to fail.
