Female for both book and screen. This is because I am female, so reading a book I identify more with a female character - also her thoughts would make more sense to me than that of a male character. Onscreen, also female, because I actually don't like movies all that much and get restless. Because of this lack of interest, I prefer it when there's other stuff I can think about while watching the movie, instead of just the plot. For a female movie character there are hairstyles, makeup and clothes to think about, more so than for a male character. An odd answer I know... but it's what I happen to think!
