EXCLUSIVE: Former CSI star and executive producer William Petersen has signed with WME. The move comes two weeks after Petersen departed Cinemax pilot Hurt People, which he had helped develop and sell. During Petersen’s nine-season stint on CSI, the crime drama was the most watched series on American television and ranked several times as No. 1 in the world. Petersen, who is partnered with long-time producing partner Cynthia Chvatal at their High Horse Films, started his career in theater before segueing to features and TV. Petersen was at UTA and continues to be repped by attorney Cliff Gilbert-Lurie.
