WGN America is signing up for another blast from the past.

The Tribune-owned network has renewed its atomic bomb drama Manhattan for a second season, The Hollywood Reporter has learned.

From Lionsgate Television, Skydance and Tribune Studios, the John Benjamin Hickey-starrer will return in 2015. In its freshman run, the well-reviewed Manhattan has averaged 420,000 total viewers on Sundays at 10 p.m. through its first 11 episodes. That's about half of WGN's first original scripted drama Salem, which also has been renewed for a second season in 2015. WGN America also presold Manhattan for a second window on Hulu Plus.

Hickey (The Big C) stars as Frank Winter, the professor who is commissioned to help lead the Manhattan Project. Olivia Williams portrays his wife, Liza, while Ashley Zukerman is Charlie, a hotshot new scientist who joins the project. Daniel Stern plays Frank's boss, Glen. Sam Shaw (Masters of Sex) created the series and exec produces alongside David Ellison, Dana Goldberg and Marcy Ross. Emmy-winning director Thomas Schlamme (The West Wing, Pan Am) also is on board as a writer-director. The drama was picked up straight to series and hails from Skydance Television, Tribune Studios and Lionsgate Television.

For Skydance, Manhattan joins Netflix's upcoming Grace and Frankie on the 2015 lineup.

Lionsgate's scripted slate consists of AMC's Mad Men and Showtime's Nurse Jackie — both ending next year — as well as ABC's Nashville, Netflix's Orange Is the New Black and FX's 10/90 comedy Anger Management.

Manhattan is WGN America's second original scripted drama. The network also is readying a Ten Commandments miniseries and has 13-episode Appalachia drama Titans as well as slave drama Underground in the works.
