Jon Favreau has posted an update on his MySpace page
First of all, as you probably already know, there is not a teaser trailer on the front of Transformers as many of you had hoped and speculated. We are, however, planning to reveal something very cool very soon. This month, in fact. In San Diego. We've secured a prime slot Saturday afternoon in the big room at SDCC. We will split an hour with Marvel and Hulk and plan to cut something together to reward the fans for their interest, support and patience. In addition to our Saturday afternoon presentation, we will be doing a signing and poster giveaway at the Marvel booth on Saturday. Paramount is also doing a rundown of its slate on Thursday which I will do my best to attend as well.
Second of all, you had questions about Iron Monger/Mandarin/Obadiah Stane. My response is read the books. We took certain liberties to keep things fresh and unexpected but we are essentially using the books to inspire our story. Iron Man fans should have no problem piecing together what's what. As far as what villians appear in this movie's storyline, I should reiterate that in the year spent developing our story we decided to treat Iron Man as a first chapter. We cover the origin story and the rise of the hero. It stands alone as a movie, but definitely leaves room for more to be told. Sequels often feel like the story was slapped together in a scramble to exploit a successful franchise. I prefer when stories are mapped out in advance. They feel less repetitive and arbitrary. Additional Iron Man movies are by no means guaranteed but, if we are lucky enough to do more, we will be ready to do them well.
Third. Cameos. I've read that Sam Jackson and Hilary Swank are Shield agents and that I myself play a Vegas security guard. There is no truth to any of these rumors.
(Well, maybe one is true.)
Seeing as Iron Man is produced by Marval, just as Fantastic Four 2, instead of a separate production company, lets just hope that Iron Man doesn't suffer from the same story, character development, and plot problems.
