Facts about William Petersen
William Petersen Biography
William Petersen is known to TV fans as dedicated crime fighter Gil Grissom, thanks to his years as the star of the CBS drama C.S.I. (2000-09). Petersen had previously played tense, obsessive lawmen in the films To Live And Die In L.A. (1985, with Willem Dafoe) and Manhunter (the 1986 "prequel" to Silence of the Lambs). The roles earned him respect but not stardom, and throughout the 1990s he took a variety of roles on stage and screen, including parts in the films The Beast (1997) and The Skulls (2000) and the TV remake of 12 Angry Men (1997, with James Gandolfini). The success of C.S.I. made Petersen a familiar face to viewers, and even after his character “left” the show Petersen had a hand in the series, serving as executive producer.
