Dr Metz is a character in the James Bond film Diamonds Are Forever. He is portrayed by Joseph Furst.
Metz is a scientist and pacifist who is an expert on light refraction. He is duped by Ernst Stavro Blofeld into helping him build a laser satellite using the smuggled diamonds capable of destroying nuclear missiles. Metz believes that Blofeld intends to use the laser to insure world peace, and thus goes along with the plan. When Blofeld’s intents are revealed as malicious, Metz asserts that he’s bluffing, but is proven wrong yet again when Blofeld activates the satellite. Whether Metz was able to escape the exploding oil rig or not is unknown.
