Diana's comments on a possible OUTLANDER movie
My take on it: She's right that the project is still at a fairly early stage, and people shouldn't assume that it will definitely happen. Also, we have Absolutely No Idea at this point who they are considering for the major roles. All the talk about Gerard Butler, Keira Knightley, and James McAvoy notwithstanding, the fact is that everyone is speculating, and no one but the casting director actually knows who they have in mind.
I'm actually relieved that Diana doesn't want to get too involved with the movie. It would take away far too much time from her writing, and that would be bad for all of us.
