Doctor Faustus is a 1967 British horror film adaptation of the 1588 Christopher Marlowe play The Tragical History of Doctor Faustus directed by Richard Burton and Nevill Coghill. The first theatrical film version of a Marlowe play, it was the only film directed by Burton or Coghill, Burton's Oxford University mentor. It starred Burton as the title character Faustus, with Elizabeth Taylor appearing in a silent role as Helen of Troy. The film is a permanent record of a stage production that Burton starred in and staged with Coghill at the Oxford University Dramatic Society in 1966. Burton would not appear on stage again until he took over the role of Martin Dysart in Equus on Broadway ten years later.
