From American Cinematographer, Samurai Tactics by Ron Magid (October 1998)
"We had great drivers, and we did some shots with the actors in the real cars during the scenes. I got the English right-hand-drive versions of the cars we were going to shoot. That way, we could have the stunt driver on the right, driving the car, and a phony steering wheel on the left for the actors, so we could photograph the actors driving' the cars in a lot of cases. We picked Jean-Claude Lagniez as the stunt coordinator and driver, and he brought in two colleagues, Michel Neugarten and Jean-Pierre Jarrier. Together, Lagniez and Neugarten had won their category at Le Mans the year before, and Jarrier was a Formula-One driver. Those guys were really fabulous. I'd tell Lagniez what I wanted to do, and he'd figure out how to do it."
