Theroux hired to pen 'Iron Man' sequel

Justin Theroux has been hired to pen the sequel to Iron Man, reports Variety.

More established as an actor for his roles in American Psycho, Charlie's Angels: Full Throttle and Six Feet Under, Theroux recently had a hand in the script for Ben Stiller's upcoming war comedy Tropic Thunder.

He is the cousin of BBC documentarian Louis Theroux.

Iron Man, Marvel's first self-funded comic book adaptation, has so far grossed more than $500 million at the worldwide box office.

Director Jon Favreau and star Robert Downey Jr. are both expected to return for Iron Man 2, which has a release date penciled in for April 2010.
