Fun film with a horrible script matched with pretty bad acting but good musical score and great on-location photography. There's not much of a story-line - the CIA(?) trying to save the last of three scientists that have developed an alternative fuel to oil from an oil baron. Lots of pretty women, well-choreographed fight scenes, steady well-paced action, and the 60s European flavor make this an okay viewing.
