"The effects are about as cutting-edge as they can be without being insane," notes [VFX Supervisor Kent] Houston, an associate of Gilliam since Monty Python days, "but our work is meant to enhance the film and not call a great deal of attention to itself. The trickery is only to aid Terry's aims."
An example of this is the establishing shot of Duke and Gonzo driving down Fremont Street to the main entrance of the Mint Hotel in downtown Vegas, which looks vastly different today than it did in 1971. "That's been done as a composite of live action and a computer-generated matte," notes [VF Coordinator Michael] Cooper, "with animated lights, more people and a very stylized sky at sundown."
