This news comes on the heels of the now dis-proven rumor that Dominic West was in talks to play Destro in G.I. Joe. IESB.net has spoken to sources at Paramount, who confirm that West isn't even on their list of contenders for the role of the Scottish arms dealer.

At the present, the confirmed cast list for G.I. Joe includes Ray Parks (Snake Eyes), Rachel Nichols (Scarlett), Adewale Akinnuoye-Agbaje (Heavy Duty), Said Taghmaoui (Breaker), Marlon Wayans (Ripcord), Sienna Miller (the Baroness) and Byung-hun Lee (Storm Shadow).
