Gregg Beam is a character in the James bond film Quantum of Solace, and is portrayed by David Harbour.
Beam, the CIA’s South American section chief, actively plots against Bond with Dominic Greene in order to secure oil rights for the United States after the Quantum-sponsored coup in Bolivia. He is first seen on a plane with Greene and Felix Leiter. Greene asks him to get rid of Bond, which Beam agrees to do.
Meanwhile, M calls the CIA to ask about their knowledge of Greene and is put through to Beam, who lies that they have no interest in him. When Greene leaves, Leiter confronts Beam about not arresting him, and Beam replies that the US cannot only work with ‘nice people’ before threatening Leiter’s job. Later, Bond telephones Felix to meet him in a bar, and Beam calls in a CIA hit team to kill Bond in accordance with Greene’s wishes. Leiter helps Bond escape. At the end of the film, it is revealed that after Greene’s death Beam was fired and Leiter took his job.
