After attending Bishop Kelly High School in Boise, Idaho, and Idaho State University, the latter on a football scholarship, Petersen became a member of the Steppenwolf Theater Company.
His film career began with a small part in in the 1981 film Thief, and in 1986 he starred as Will Graham in Manhunter (later to be remade as Red Dragon). In a move perhaps indicative of his career choices, Petersen is alleged to have passed on a part in Oliver Stone's Platoon, as it would have kept him away from his family. Instead, he worked on the 1987 made for TV movie Long Gone. In the 2000 release The Contender, Petersen played the role of Governor Jack Hathway. Hathaway is a candidate for Vice President following the death of the incumbent.
From 2000 on, Petersen stars as Gil Grissom in the successful CBS crime drama CSI: Crime Scene Investigation.
Petersen, who has one child from a previous marriage, married longtime girlfriend Gina Cirone in June of 2003.
