East 15 Acting School (East 15) is a leading British drama school in Loughton, Essex. The main Loughton campus occupies an 18th-century house, Hatfields, and has its own theatre, the Corbett, which is adjacent. The Corbett Theatre is an adaptation of a 15th-century barn. The re-building and equipping of the theatre was largely funded by the actor, and alumnus of Joan Littlewood's Theatre Workshop, Harry H. Corbett.
