Who creates the character?

Characters themselves are created by three people, the writer, the director (often, especially in student films, the same person) and the actor. Often the way the actor portrays the character is pivotal to how well the character ends up working. It's not just a matter of good actors or bad actors, it's more what the actors turns the character into, and it's almost always a completly different idea than you, as the writer, had in your head. Frank, for example, in Isolation, was never intended to be as big as he was, but he became famous simply because John played him so creepily. Jack, as another one of my favourite examples, was a joint creation between me and Dylan, the actor who plays him. Neither of us could honestly tell you who's creation he was because he's both. We just kept adding to the character until he became a character weird, wonderful, and screwed up enough to develop his own cult following and blog. (I've actually locked myself out of that blog and it has no posts, but I'll set up a new one soon) We actually put a lot of work into the main character of Johnny as well, but his character is far less over the top so it's not so obvious. Bit of a shame really.

Now I think about it I could probably write a book about this damn movie, going into details on the characters, the actors, the experiences, what worked, what didn't. Maybe I should.
