Thomas William Selleck (born January 29, 1945) is an American actor who became a cultural icon as private investigator Thomas Magnum in the hit series Magnum, P.I. (1980–1988), which earned him five Emmy nominations and a win in 1984. He continued his television dominance by starring as NYC Police Commissioner Frank Reagan in Blue Bloods (2010–2024) and as detective Jesse Stone in nine films based on Robert B. Parker's novels (2005–2015). In movies, he won audiences over in blockbuster comedies like Three Men and a Baby (1987) and its sequel, while TV fans fondly remember him as Monica's love interest, Dr. Richard Burke, in Friends. Interestingly, the 6-foot-4-inch star served as a sergeant in the California Army National Guard from 1967 to 1973, and later became a prominent NRA spokesman. Born in Detroit and raised in Los Angeles, he was a college basketball player at USC before dropping out to study acting after a drama coach suggested it—starting a career that has lasted over five decades.
