Argo triumphs at Critics' Choice Awards

Hostage drama Argo was the big winner at this year's Critics' Choice Awards, hours after director Ben Affleck missed out on an Oscar nomination.

Affleck jokingly "thanked the Academy" as he accepted best director, but added: "This is the one that counts." The movie was also named best film.

Oscar favourites Daniel Day-Lewis and Jessica Chastain won the best actor and actress prizes respectively.
