With the critical and box office success of "Iron Man," it's no wonder Marvel wants to get the sequel party started.

The trades are reporting that Marvel is finalizing talks with Justin Theroux about him penning the script for "Iron Man 2."

With only one script credited to his name (a Ben Stiller action-comedy at that), why would Marvel choose him over the scribes of the first movie?

We'll know when the sequel comes out in April 2010.
