Porter Ranch is an affluent neighborhood in the northwest region of the San Fernando Valley region of the city of Los Angeles, California. Much of Porter Ranch is master-planned new communities, with many gated areas. Large portions of the 1982 blockbuster film E.T. the Extra-terrestrial were filmed in Porter Ranch. The Steven Spielberg classic includes several shots looking down on the Porter Ranch neighborhood beneath the ridge in Palisades Park. Brasilia Dr., Killimore Ave. and Granada Circle appear most often in E.T. Porter Ridge Park, at the north end of Reseda Blvd., was used for the famous park scene at the end of the movie. That park is now known by locals as "E.T. Park."
Most residents commute by car to business hubs of Simi Valley, Downtown Los Angeles and the commercial hub of Woodland Hills, at the San Fernando Valley's southwest corner. The community is also close to the Chatsworth and Northridge Metrolink stations that link to Downtown Los Angeles and Ventura County.
