Starz has ordered two more seasons of the hit time-travel saga Outlander from developer/executive producer Ronald D. Moore and Sony Pictures TV. This is the first multi-season pickup for the series, assuring it will run for several more years, according to Starz. The renewal comes weeks after April’s premiere of the series’ second installment.

The third season will be based on the third of the eight books in Diana Gabaldon’s Outlander series, entitled Voyager, followed by Season 4 based on the fourth book in the series, Drums of Autumn.

“’Outlander’ is like nothing seen before on television,” CEO of Starz Chris Albrecht. “From its depiction of a truly powerful female lead character, to the devastating decimation of the Highlander way of life, to what is a rarely seen genuine and timeless love story, it is a show that not only transports the viewer, but inspires the passion and admiration of its fans. On this 25th anniversary of the publication of the first book in the U.S., we are thrilled and honored to be able to continue the story that began with author Diana Gabaldon, and is brought to life by the incredibly talented Ronald D. Moore. There are no better storytellers for ‘Outlander’ than this team, both in front and behind the camera.”

“The world of Jamie and Claire is expansive and emotionally complex. The audience has rewarded Outlander with their praise and loyalty, and we know we will deliver the best seasons yet in the years ahead,” said Jamie Erlicht and Zack Van Amburg , Presidents, U.S. Programming and Production, Sony Pictures Television. “Starz has been an incredible partner and has truly helped shape this into one of the most iconic premiere series on the air today.”

Outlander received three 2016 Golden Globe nominations, including Best Drama Series, Best Lead Actress and Best Supporting Actor.

The first 16-episode run of Outlander, filmed on location in Scotland, debuted in August 2014 with the season averaging 5 million multiplatform viewers per episode and regularly ranking in the top 10 weekly cable programs among women throughout the season.

The Outlander second season premiere episode more than doubled viewing as compared to the Outlander first season premiere episode, setting a new Starz record for an original series/season premiere (on Live +SD, Live +3, and Live +7). Through seven episodes in season 2, the series has also been a top two rated show across all of cable among women 18+ (Nielsen Live +3 F18+ ratings).
