Book excerpt: Refocus: The Films of Amy Heckerling is the first book-length study of the work of Amy Heckerling, the phenomenally popular director and screenwriter of Clueless and Fast Times at Ridgemont High. As such, the book constitutes a significant intervention in Film Studies, prompting a reconsideration of the importance of Heckerling both in the development of Teen cinema, and as a figure in Hollywood comedy. As part of the Refocus series, the volume brings together outstanding original essays examining Heckerling's work from a variety of perspectives, including film, television and cultural studies and is destined to be used widely in undergraduate teaching.
