Marvel Studios has reportedly tapped Justin Theroux to pen the sequel to Iron Man.

According to Variety, the comicbook giant's film division is close to a deal to bring back director Jon Favreau and star Robert Downey Jr. The hope is to release in April 2010.

Iron Man was Marvel Studios' first self-financed picture, so it's no surprise that the studio is looking to get another installment into theaters as quickly as possible.

Marvel Studios, however, isn't being quick to confirm any deals around the project, saying it doesn't comment on rumors.
