On the heels of Outlander’s series premiere on Saturday, Starz has renewed the time-travel saga from developer/executive producer Ronald D. Moore and Sony Pictures TV for a second season.  Season 2 will consist of at least 13 episodes and will be based on the second book in Diana Gabaldon’s bestselling Outlander series, entitled Dragonfly In Amber. Unlike HBO’s fantasy series Game Of Thrones, which is catching up with author George R.R. Martin on source material, the Starz romantic drama has long ways to go — Gabaldon has written eight Outlander books so far. Outlander‘s pickup fits Starz’s pattern of early renewals — dramas Power and Da Vinci’s Demons were renewed for a second season the week following its series premiere. Several other series, Boss, Magic City, Spartacus and most recentlyBlack Sails, were given second-season pickups ahead of their series debuts.

The premiere episode of Outlander‘s 16-episode first season has delivered 5 million views in its first week. Additionally, it was No. 1 in Nielsen Twitter Ratings among all television series on premiere day. “The overwhelming support Outlander has received from the fans, viewers and critics made the decision for us to go ahead with the second book a very easy one,” said Starz CEO Chris Albrecht. Moore and Jim Kohlberg executive produce Outlander, which is filmed on location in Scotland and produced by Tall Ship Produs, Story Mining and Supply Co. and Left Bank Prods. in association with Sony TV.
