CSI veteran William Petersen has joined the cast of the 1940s-set drama series Manhattan for Season 2, WGN America announced Thursday.
Produced by Lionsgate Television, Skydance Television and Tribune Studios, Manhattan will begin shooting its sophomore season in New Mexico in April for a debut later this year on the cable television network.
Petersen will play U.S. Army Colonel Emmett Darrow, the enigmatic new ranking military officer at Los Alamos.
"A deeply religious and patriotic man, Darrow feels called by God to usher in the atomic future, and to spread American values across the globe," a news release said.
The show stars John Benjamin Hickey, Olivia Williams, Daniel Stern, Ashley Zukerman, Rachel Brosnahan, Katja Herbers, Alexia Fast and Christopher Denham. Created and written by Sam Shaw and directed by Thomas Schlamme, Manhattan is about the people working to build the world's first atomic bomb.
