Where exactly were all these references that got distracting??
And only Favreau knows why he left. As far as he wanting to make his own movie, Marvel didn't even let him do that in the beginning, the original villain was going to be Mandarin, then it got changed to Crimson Dynamo which again got changed to Iron Monger. If Favs really wanted, he would've left mid production in the first one. And speaking of Mandarin he had no clue on how to make him for the big screen, look at his interviews when he's talking Mandarin, he gives a different response in each, from making him tech based to some magical wizard. I'm sure that factored in his departure.
But anyways this is the Cap thread and we're here to talk about that awesome trailer.
