Brian Manion Dennehy (born July 9, 1938) is an American actor of film, stage, and television. After gaining recognition for portraying the corrupt Sheriff Will Teasle in First Blood (1982), Dennehy went on to win one Golden Globe, two Tony Awards and six Primetime Emmy Award nominations.
Dennehy was born in Bridgeport, Connecticut, the son of Hannah (Manion) and Edward Dennehy, a wire service editor for the Associated Press. He has two brothers, Michael and Edward. He is of Irish ancestry and was raised Roman Catholic. The family relocated to Long Island, New York, where Dennehy attended Chaminade High School in the town of Mineola.
Dennehy enlisted in the U.S. Marine Corps in 1959, serving active duty on Okinawa until 1963. In numerous interviews, Dennehy has claimed to be a Vietnam veteran who served a 5-year tour in Vietnam and recounted harrowing tales of his combat there, but according to the book Stolen Valor, Dennehy never served in Vietnam at all and never saw active combat. Stolen Valor and other books surmised that fabrications of PTSD and traumatic events in general were intended to gain honor or recognition. The author of Stolen Valor wrote to Dennehy regarding the discrepancy, but received no reply from the actor, although Dennehy later admitted in an interview that he had lied about his service and apologized for it. Nonetheless, he later repeated the same story about serving in Vietnam in an interview with Joanne Kaufmann of the Wall Street Journal.
