Just in from /Film [1], which is citing the IMPA [2]:

The final theatrical one-sheet for Jon Favreau’s Iron Man has hit the web. I’m not a big fan of the floating head ascetic, and this is kind of an off-shoot of that overused marketing style. But at the same time I also understand that you can’t just sell the movie with a bad ass photo of Iron Man. The movie studio is playing it smart and hedging their bets by putting some sparkle out there to attract the non-comicbook geek masses.
