William Peter Moseley[1] (born 27 April 1987) is an English actor, currently best known for appearing as Peter Pevensie in the film series The Chronicles of Narnia. Previously he had a small role as Forrester in a 2002 adaptation of the novel Goodbye Mr. Chips, and had appeared as an extra in Cider with Rosie (1998).

William Moseley was born in Sheepscombe, Gloucestershire, England in the Cotswolds. He is the son of Julie and Peter Moseley, a cinematographer.[2] Moseley is the eldest of three children: Daisy (born 1989) and Benjamin Moseley (born 1992). Moseley attended Sheepscombe Primary School from September 1991 to July 1998, and then continued his education at Wycliffe College with final year at Downfield 6th Form College, Stroud (which is part of Marling School and its next door neighbour Stroud High School). He had to repeat upper sixth because he had taken so much time off school while filming The Chronicles of Narnia: The Lion, the Witch and the Wardrobe. At the age of 7, William listened to the Chronicles of Narnia audio tapes. He read the books eight years later in preparation for his role as Peter Pevensie in the film adaptation The Chronicles of Narnia: The Lion, the Witch and the Wardrobe in 2005. Casting director Pippa Hall was responsible for casting William as an extra when she was filling roles for Cider with Rosie (TV) back in 1998. Seven years later, when casting for The Chronicles of Narnia: The Lion, the Witch and the Wardrobe in 2005, she remembered him and recommended him for the role of Peter. From the first day of auditioning for the role of Peter Pevensie in The Chronicles of Narnia: The Lion, the Witch and the Wardrobe it took a further eighteen months before he officially won the role and was cast.[citation needed]

Moseley will be starring in A Great Education, opposite Emma Roberts.[3] William Moseley has joined the Stand Up to Cancer program "Change the Odds" featuring many other young actors.[4]
