Yesterday we reported that Mickey Rourke had signed up to play a drug lord in Sylvester Stallone's action epic The Expendables; well Variety is reporting today that Jon Favreau wants him to play the main Russian villain in Iron Man 2, and the actor is reportedly now in negotiations with Marvel for the role. The criminally underused Sam Rockwell is also speaking to the new studio about a role in the production. The script is being penned by actor and Tropic Thunder scripter Justin Theroux as we speak. The first film grossed a staggering $600 million worldwide, making Robert Downey Jr. one of the most bankable stars on the planet, and gave Marvel their first solo smash.
