http://bitly.com - Each video is slightly different from what we see in the film. Mainly its minor action beats that could have been too expensive or cut for pacing issues. That Mandarin death is really worth discussing though. Based on this it seems Trevor was going to inject himself with Extremis and explode from doing it incorrectly. In keeping with the character I think that might have been a really funny twist but by not doing it Marvel kept the option of bringing him back open. In the film we last see Trevor being taken into custody.Though I know Killian was the brains behind the Mandarins plot in Iron Man 3 I keep hoping for a double twist where Trevor is the persona the Mandarin is who you think he is and it was he who was playing Killian all along.
