Fred Dalton Thompson spent 25 years as an active Nashville and Washington, D.C., attorney before making his film debut playing himself in a 1985 retelling of the true tale of a Tennessee woman who took on the state's crooked governor in Marie. When Thompson won more acclaim than the film's stars Sissy Spacek and Jeff Daniels, he decided to add character actor to his resumé.
Since then he has appeared in numerous major features. Standing 6'5, he is a commanding presence and is usually cast as an authoritarian. Thompson put his film career on hold when he made a successful bid to become a Tennessee senator in 1994, then picked up where he left off when his term ended, playing DA Arthur Branch on Law & Order, along with other supporting film roles. ~ Sandra Brennan, All Movie Guide.
