When writing something, I usually find (often without realizing it until well into my story) that I’ve “cast” an actor in at least one, if not more, of the chief roles. For example, the screenplay I’m writing now is based on a play I wrote last year, and somewhere in between starting and finishing writing that play, I realized it was Ewan McGregor’s voice in my head as the main character. A young Ewan McGregor, mind, since the characters are not long out of university, but him all the same.
With The K-Pro I had Benedict Cumberbatch in mind for David Styles, though in retrospect, were I to cast this as a film, I’m not sure I’d give him the part. Later in the story, I sort of had Emily Blunt in mind for Liz, and certainly Judy Dench as David’s mother . . . Everyone else I picture quite clearly but haven’t really found comparable actors for the roles. (Maybe that guy who played Lutz on 30 Rock for Craig?)
Of course, if you ever see a movie based on a book, it always fashions (or refashions) your mental image of the book. Sometimes, if I’ve read a book and then see the movie, I end up with two separate ideas in my head: my original and the one that has been fabricated for the multitudes. If I see the movie before I read the book, I’ll almost always simply picture events from the film version as I read. (Almost always.)
And then it’s somewhat surreal to see something you’ve written become a cast and produced—a concrete play or film. That changes things, too. I don’t know what I’ll think or feel when they make this screenplay (they’ve already cast one lead) . . . Will I keep picturing Ewan McGregor or will I be able to shift my interior perspective? I’ll literally have to wait and see.
