Producer says 'Argo' was 'tricky' to promote

Grant Heslov admits 'Argo' was a "tricky" film to market.

The producer says he wasn't sure how bosses could promote the film - which stars Ben Affleck and tells the story of the 1980 joint CIA-Canadian secret operation to extract six fugitive American diplomatic personnel out of revolutionary Iran - because it doesn't fall into one category and has a strange-sounding title.
