Extras?

Yes, it's true I'm going to be a Nim's Island extra (along with my husband Tom, and Kerry Millard, the book's illustrator) but I'm afraid I have no idea how you get to be one if you didn't happen to write the book the film was based on!

I was going to say say the 'usual channels' but to be honest I have no idea what those are.

So... sorry to everyone who thought I might be able to help,but I'm afraid I honestly can't.
