Jafar Panahi's "Crimson Gold" begins with the armed robbery of a Tehran jewelry store, an event captured in one motionless shot as if by a security camera, albeit one that has been set up for artistic effect rather than efficient surveillance. Gunshots are exceedingly rare in Iranian movies, and the two that are fired in the opening moments reverberate with particular force, even though the crime they aggravate looks banal and amateurish.
