When it came to adapting Outlander for television, producer Ronald D. Moore knew it was all about the fans.

Writer Promises 'Outlander' Romance Will Heat Up This Season 

"I started the project thinking how we were going to reassure the fans that we were going to honor the spirit of the book," Moore told Scotland Now on Monday. "So it's great to see that they've embraced what we've done."

Outlander is based on the epic time-traveling, historical romance series by Diana Gabaldon. The story had possessed a strong following from readers for decades before Moore brought the idea to Starz and the producer used this point in selling the show to the network.

"I emphasized that point," said Moore of that first meeting with Starz. "If we could capture the fan base, that creates its own base. If it's a hit with the fans, people will be more inclined to check it out."

Of course, it helped that Moore and his wife, costume designer Terry Dresbach, were already part of that fanbase. Both knew the books and respected the material.

"It's a great adventure story," noted Moore. "A really good yarn with great twists and turns and you want to know what happens next."

"There's this great female character…[and] weaving in and out of actual historical events is always really interesting," he added.

Outlander will return on Starz for the remainder of its first season on Saturday, April 4 at 9 p.m. ET/PT.
