In 1962, filmmaker François Truffaut (1932-1984) was a rising star in the world of cinema, having directed a small but significant number of acclaimed pictures, such as “The 400 Blows” (1959) and “Jules and Jim” (1962). Yet, when the brash young French auteur was asked to name the greatest influence on his work, he cited a veteran of the field, someone many years his senior, the legendary British director Alfred Hitchcock (1899-1980).
