Double Agent 73 (1974) is the follow up to Deadly Weapons (1973) and again features the aptly named Chesty Morgan in an eye-popping mamnificant performance. Whereas before Chesty killed with her bazooka-sized boobs, she now plays a secret agent/assassin with a camera implanted in her jugs, which naturally gives the film ample opportunity to show off her ample treasure chest. Along the way viewers are treated to lots of Chesty's fancy camerawork and even a bitch slap with her breast if someone gets in her way. Besides Chesty's megalithic mams, famed stripper Blaze Starr provides some backup boobage in one scene. That's double trouble.
