Ben Affleck's Iran hostage drama 'Argo' has won the Outstanding Performance by a Cast in a Motion Picture gong at the Screen Actor's Guild Awards.
The awards often share many of the same winners as the Oscars at the end of February, and may now see 'Argo' slip into a better position ahead of the likes of 'Lincoln' and 'Silver Linings Playbook', both of which featured in the same category.
