 Initial filming of the car chase sequence resulted in disappointing action sequences.While moving the car between shoots, Lotus test driver Roger Becker so impressed the crew with his handling of the car that for the rest of filming on Sardinia, Becker became the stunt driver.The motorcycle sidecar missile used in one chase sequence was built by film staff at Pinewood and used a standard Kawasaki Z900 and a custom made sidecar outfit.
