"Outlander" executive producer Ron Moore ("Battlestar Galactica") and star Sam Heughan showed up wearing kilts, an ode to the show's Scottish setting.
"We all know who wears the pants in this relationship," joked co-star Caitriona Balfe.
"Outlander" follows the story of Claire Randall (Balfe), a married combat nurse from 1945 who time travels without explanation back to 1743 where she is forced to marry Jamie Fraser (Heughan), a Scottish warrior.
Gabaldon gave the TV series her blessing, voicing her support for Moore's approach and complimenting producers for sending her scripts and soliciting her opinion on occasion. She'll also have a cameo appearance in an episode.
"I'm not reinventing it," Moore said. "It's a matter of adapting it. There is an audience for it, a dedicated base of fans who love these books and I take that obligation seriously. I want to give them their story but I do have to translater it into a different medium. But in the writers' room we always start with th ebook. What's the book version of events? And then we go from there."
To say the book series has fans is an understatement. Starz showed footage of fans -- mostly middle-age women -- at a book convention carrying homemade signs and professing their devotion to the romantic story.
"I don't think I was aware of the magnitude of the fans and how enthusiastic they were," Balfe said. "It's a dream role."
Gabaldon said fans have been dying for a screen adapatation of the story for years.
"They want to be Claire," she said, before gesturing to Heughan, "and they sort of want to lick him."
