WGN America has released an extended trailer for the first season of its upcoming drama series “Manhattan.”

Set in the 1940s, “Manhattan” follows the events of a small New Mexico town filled with scientists recruited to work on the Manhattan Project, the development of the first nuclear bombs. John Benjamin Hickey stars as lead scientist Frank Winter, who, along with his wife Liza (Olivia Williams) and daughter Callie (Alexia Fast), must work through the danger and deceit occurring in the highly secure outpost.

Daniel Stern, Ashley Zukerman, Rachel Brosnahan, Katja Herbers, Christopher Denham, Harry Lloyd, Michael Chernus and Eddie Shin also star. Lionsgate Television, Skydance Television and Tribune Studios are producing.

In his reviewVariety’s Brian Lowry spoke positively about the show’s premise, saying, “‘Manhattan’ earns points for being serious and ambitious, while creating a strong sense of atmosphere and place in the isolation — and paranoia — in which the families must exist,” though also noted that the show is missing “the elusive spark necessary to make (its elements) genuinely pop.”

Created by “Masters of Sex” writer Sam Shaw and directed by “The West Wing’s” Thomas Schlamme, “Manhattan” is WGN America’s second original scripted series, following “Salem,” which was renewed for a second season following its April premiere.

“Manhattan” is scheduled to premiere on July 27 at 9 p.m. ET.
