Anna Percy - Originally from the Upper East Side in Manhattan, she moves to Los Angeles with her father to finish her senior year and then apply for an internship while hoping to change her boring life. She is serious and intelligent, and frequently refers to the imaginary "This Is How We Do Things Big Book, East Coast WASP Edition" - a set of rules she grew up with in her patrician family. Her parents, Jane Cabot and Jonathan Percy are divorced and she has a somewhat strained relationship with her father that slowly begins to improve. She is a leggy, blonde, patrician beauty, who is often compared to Grace Kelly. She is often referred to as a "tight-ass" by other characters because of her tendency to play things safe and not take risks. Anna is usually very careful with her trust, but knows her way around people. Before moving to L.A., Anna planned to major in English at Yale but quickly found herself to have a talent for screenwriting. Anna is not particularly overwhelmed or impressed by the L.A. lifestyle, nor by the celebrities the characters encounter or talk about throughout the series. She and Sam become fast friends at Beverly Hills High although Anna intensely dislikes Sam's other friends, Dee Young and Cammie Sheppard.
