John Scot Barrowman is a Scottish and American actor, author, presenter, singer and comic book writer. He is known for his roles as Captain Jack Harkness in Doctor Who and its spin-off Torchwood, and as Malcolm Merlyn in the Arrowverse.
Born in Glasgow, Barrowman moved to the US state of Illinois with his family at the age of eight. Encouraged by his high school teachers there, he studied performing arts at the United States International University in San Diego before landing the role of Billy Crocker in Cole Porter's Anything Goes in London's West End. Since his debut, he has played a number of roles in various musicals both in the West End and on Broadway, including Miss Saigon, The Phantom of the Opera, Sunset Boulevard, and Matador. After appearing in Sam Mendes' production of The Fix, he was nominated for the 1998 Laurence Olivier Award for Best Actor in a Musical and, in the early 2000s, returned to the role of Billy Crocker in the revival of Anything Goes. His most recent West End credit was in the 2009 production of La Cage aux Folles.
Alongside his theatrical career, Barrowman has appeared in films such as the musical biopic De-Lovely and musical comedy The Producers.
