The DailySuperHero.com: Fans have wanted it and Iron Man 3 writer Drew Pearce and writer/director Shane Black wanted it but the Mouse God in the sky said, "NO." Iron Man's famous "Demon in a Bottle" comic book story arc was initially a basis for Iron Man 3 but Disney didn't want to show Tony Stark dealing with alcoholism and drinking heavily on the big screen.
And Disney strikes... I wonder how else they'll censor Marvel films...
the demon in the bottle was actually referring to his alcholism and for once i would agree with disney that it wont work. they showed enough already in ironman 2 and in my opinion was not a pleasant scene with him and his partner fighting in a party..easily the weakest scene in the movie.
