About Mike Farrell
Michael Joseph Farrell Jr. (born February 6, 1939) is an American actor, best known for his role as Captain B.J. Hunnicutt on the television series M*A*S*H (1975–1983). In addition, Farrell was a producer of Patch Adams (1998) starring Robin Williams, and he starred in the television series Providence (1999–2002). Farrell is also an activist and public speaker for various political causes. He has been the President of Death Penalty Focus since 1994. He is a long-time opponent of the death penalty. In 2001, Farrell said of the work: "I've wept many times. But I keep finding people who inspire me—some of them on death row, and more of them in the trenches, in the courts, in religious circles, fighting against the death penalty." Farrell has helped raise defense funds for inmates he believes are innocent. Farrell was recruited for the newly created role of B.J. Farrell won the part of B.J. over two other finalists for the role, Alan Fudge and James Cromwell (both of whom guest-starred in the series subsequently).
