Day Dream about the film version of HoWG of course!
Here's my cast:
Jeanane Garofalo (she was in "The Truth About Cats and Dogs" with Uma Thurman) as "Lucy" (yes, my main character is called Lucy!) . She's a little bit too old but I can't think of a brunette British character actress in her twenties that fits!
Jack Davenport as "Dan" (Again he's a tiny bit too old but hey, I'm not ageist)
Bob Hoskins as "Saint Bob" (perfect!)
David Thewlis as "Brian"
Honor Blackman as "Mrs Humphreys-Smythe"
And I can't cast "Claire" because I can't think of a single actress in her late teens/early twenties that is a size 16/18 (how sad it that?)
So who would be in the movie of your book?
