BUtterfield 8 is a 1960 Metrocolor drama film directed by Daniel Mann, starring Elizabeth Taylor and Laurence Harvey. Taylor, then 28 years old, won an Academy Award for her performance. The film was based on a 1935 novel written by John O'Hara in the wake of the success of his critically acclaimed Appointment in Samarra. The unconventional title of the novel and film (capitalized "B" and "U") derives from the pattern of old telephone exchange names in the United States and Canada. Until the early 1970s telephone exchanges were commonly referred to by name instead of by number. BUtterfield 8 was an exchange that provided service to ritzy precincts of Manhattan's Upper East Side. Dialing the letters "BU" equates to 28 on the lettered telephone dial, so "BUtterfield 8" would equate to 288 as the first three digits of a seven-digit phone number.
