I would never describe Charlotte as a prude - maybe at the start, but that was in comparison to the other girls. She wasn't willing to do the stuff they were doing - and I mean, thank goodness!
I find that when I play reality-based characters, it is only as fun for me if I have a lot of time to do research. If I don't it just isn't exciting but if I do, it can be fun because I can learn about that person and the world that they live in and I can become somebody else.
My first car was a 1976 Toyota Corolla Liftback in red, like the one in 'The Blues Brothers.' I painted a Union Jack on the roof. I was absolutely in love with it until I destroyed it, which broke my heart!
