Our sister blog, Cinematical, is covering Comic-Con in San Diego and lo and behold, what did they spot out in front of the convention center? Tony Stark's Audi R8. This is just an early tease for Fanboy Nation, and this major product tie-in that will also see several other Audis cross the screen in Iron Man. The silver R8 was parked out front sporting the plate "Stark 4." Priceless. Robert Downey, Jr. portrays the armor-sporting hero in this newest comic-book-to-big-screen adaptation, which, if the reports on the footage shown at the convention are accurate, is going to kick ass.
