Based on the book series from Diana Gabaldon, Outlander follows Claire Randall, a married combat nurse from 1945 who is mysteriously swept back in time to 1743 and forced to marry Jamie Fraser (Sam Heughan), a young Scottish warrior.
The Games of Thrones alum will play the roles of both Frank Randall and Jonathan "Black Jack" Randall. Frank is Claire's 20th century husband, a professional historian with a deep interest in the 18th century and his own genealogy. Jonathan is Frank's ancestor from the 18th century, a captain in the English Army who's a dark and violent man.
Battlestar Galactica's Moore will write and executive-produce with Jim Kohlberg.
Menzies is best known for playing Edmure Tully, whose wedding was "celebrated" in the shocking penultimate episode of Game of Thrones last season.
The 16-episode series, which will begin filming in Scotland this fall, is slated to premiere in 2014. Will you watch?
