Thief, 1981
John Santucci, the actor on the right playing a plainclothes police officer, was in fact a former Chicago jewel thief. “The burglary tools used throughout the film (such as the hydraulic drill used in the opening sequence) were not props, but actual tools which the actors were trained to use. The tools were supplied by actual thieves who served as technical consultants on the film, principally John Santucci, who also portrays Sgt. Urizzi on screen.” (via) Santucci went on act in several other Michael Mann productions, most notably as mob henchman Pauli Taglia in Crime Story.
