Apparently, they are a couple of romance novel characters, and a movie is/was made, based on the book. Since there's a series of books, if the movie does well, I would not be surprised to see them continue in sequels. from http://blogs.myspace.com/index.cfm?fuseaction=blog.view&friendId=313934208&blogId=346928097 , the January 13, 2008 blog entry entitled: "Diana Gabaldon’s Outlander Saga": "To all of you who have read Diana Gabaldon's Outlander saga,I am so excited about the movie!Gerard Butler and Rachel Weisz are the main characters.If you haven't read them,get your buts in gear and get to the nearest book store!!!!!Packed with emotions,love,sadness,adventure,fighting,time travel,and especially men in kilts!They portray Jamie and Clair Fraser,Clair traveled back in time while on a trip to Scotland,they met and fell in love,but Clair was forced to go back to her own time.Jamie almost died in the battle of Culloden,but they continued to love each other for almost 20 years,unable to see or touch each other.Living in different times their lonilness touched their very souls.The only thing that kept them carrying on without each other was the hope that they would find each other again.You will absolutely love the saga and will be unable to put each book down."
