Craig Mitchell is an MI6 traitor in the film Quantum of Solace, and is portrayed by Glenn Foster.
Mitchell is M’s bodyguard and has been so for the past five years. Throughout his career, he has made considerable contributions to charity and eventually winded up broke. He is also a double agent working for Quantum, which MI6 is unaware of until when interrogating Mr White in the Siena safehouse.
Mitchell shoots and kills another agent and lets White escape. Bond chases him through a network of underground tunnels beneath the city and then up unto the rooftops during the Palio di Siena, culminating in a fight in the Siena Art Gallery. He is killed when Bond grabs his gun and shoots him.
