The Stark-snark is one of the characters most loved qualities, but like almost all the preview footage to date, the latest trailer for the threequel dials up the serious factor. Granted this is only a 2 minute look and hence this speculation could prove premature, but at the very least we can expect the snark to be significantly reduced this time out. Its important to acknowledge that the Avengers assembling wasnt just a game changer for superhero movies, it was a massive event for the heroes themselves. Downey Jr. already looks to be doing a great job of portraying Tonys inner struggles, and it will be interesting to see just what effect the climactic events of The Avengers had on the other members of the team.
