We have finally provided for you what you really want. A trailer for the new Iron Man film. Granted, this is the trailer from the Comic-Con 2007 show less than 2 months ago, but it is the official trailer from what we have heard.
According to the director, the trailer will be shown across all venues on the 10th and 11th of September.

The only possibility is that the trailer shown in 3 days time is merely a teaser, and the one below will be the full theatrical trailer. I guess we will all see for sure in 3 days! At any rate, enjoy!
