Beginning with perhaps the most celebrated tracking shot in history, Orson Welles’s bravura film noir is a shadowy tale of murder, malevolence and police corruption.
When a car bomb explodes on the US-Mexican border, Mike Vargas (Heston), a Mexican official investigating drug trafficking, is drawn into the case. Vargas is convinced that American cop Hank Quinlan (Welles) is planting evidence to incriminate the prime suspect, and he becomes obsessed with exposing Quinlan as a rotten apple. Quinlan then seeks revenge by conspiring with gangsters, who terrorise Vargas’s wife Susan (Leigh).
Welles gives a stunning performance as a man increasingly depleted of humanity, and his deliriously daring thriller with a dark emotional core is one of the greatest of its genre.
