With "Iron Man" collecting $565.1 million worldwide since its debut on May 2, Mark Fergus, Hawk Ostby, Arthur Marcum and Matthew Hollaway can surely be considered to be successful in delivering the comic book adaptation to the big screen. In spite of that fact, Marvel Studios apparently have taken a surprising decision on bringing a new writer to tackle "Iron Man 2".

Latest report claimed that the production company have brought in actor/writer Justin Theroux to pen the script of the sequel. Aside from the fact that the studio have hired the "Tropic Thunder" co-scribbler, other details regarding the matter aren't being shared out. In fact, Marvel haven't come out with any confirmation on the signing of Seamus O'Grady's depicter in "Charlie's Angels: Full Throttle".

Earlier, it has been reported that Marvel have finally reached a deal with director Jon Favreau for him coming back to helm the second film. Meanwhile, on the casting report, the studio are said to be closing in to sign a deal with the movie's star Robert Downey Jr. for his return. The sequel itself has been slated for April 30, 2010 release.
