Well as far as voicing Rocket Racoon I hope he has a british accent or a scottish accent. So I vote for David Tennant or Vinny Jones.
As far as this happening I hope they have Drax and Quasar as well as Rocket and Groot. This would be such an epic film on so many levels. Hell I would love to see a cameo of the Silver Surfer or as he's know in the 31st century the Keeper of the Uninverse. How awesome would that be.
And why do people keep saying that Iron Man was an obscure character. Of course he was not known like Supes, Bats or Spidey, but he wasn't the Blue Beetle









are forgetting their early 90's comic run that Jim Valentino started...reaching 62 issues, unfortunately it died after Valentino left to get Image started in '92 and launched his series ShadowHawk. I have all issues sitting in plastic....maybe it will become time to sell these little treasures ;)
