Poor Alan
Someone on alanrickman posted a link to IMDB that has trivia about An Awfully Big Adventure. I should probably go back and read all the trivia for his movies since I didn't know this before.
I think Alan's the kind of guy who is very generous with himself but it doesn't take a lot for him to lose respect for you. But how true this is, I don't know:
SPOILERS FOR AN AWFULLY BIG ADVENTURE!!!
Georgina Cates had unsuccessfully auditioned for the part of Stella under her real name of Clare Woodgate. Frustrated, she dyed her hair, reinvented herself as a 16-year-old Liverpool girl called "Georgina Cates", and landed the role.
Alan Rickman was reportedly upset to find out that Georgina Cates had lied about her age (she was in her early 20's but stated she was only, indeed, 16) in order to land the role of Stella. He had gone out of his way to be extremely gentle around her during their intimate scenes because of her perceived age.
