Emma Watson was born in Paris, France to parents, Jacqueline Luesby and Chris Watson. At the age of five, Emma's parents divorced and she then moved to Oxfordshire, England with her mother and younger brother, Alexander.
Her father has a son named Toby, and identical twin daughters, Nina and Lucy, and her mother's partner has two sons. Emma spent much of her childhood residing in England with her mother and stepfather, younger brother, and two stepbrothers.
She trained at the Oxford branch of Stagecoach Theatre Arts, a part-time theatre school where she studied singing, dancing and acting. By the age of ten, she had performed and taken the lead in various Stagecoach productions and school plays, including "Arthur: The Young Years" and "The Happy Prince". 
Casting agents found Emma through her Oxford theatre teacher, and the producers of the film were impressed by her confidence and her natural acting abilities. After eight consistent auditions, producer David Heyman told Emma and fellow applicants, Daniel Radcliffe and Rupert Grint, that they had been cast for the roles of the three leads, Hermione Granger, Harry Potter and Ron Weasley.
