answer: Playtime
context: Title: Gai dimanche
  Passage: Gai dimanche (English: "Fun Sunday" ) is a 1935 three reel film written by and starring Jacques Tati and his friend Rhum.  The pair star as down-and-outs who try to generate funds by providing an impromptu leisure tour in a rickety bus they wrangle use of for free.  Released in 1935 and rarely seen today, the film offers brief glimpses and hints towards methods Tati would begin to perfect in his films more than a decade later.  The short was included in the Criterion Collection's "The Complete Jacques Tati" box set, in a disc containing several short films that Tati either directed or starred in.
  Title: Richard Boston
  Passage: Richard Boston was born in London and brought up on a Kent farm.  He was educated at Stowe School, Regent Street Polytechnic and King's College, Cambridge.  During the early 1960s he taught abroad in Sweden, Sicily and Paris.  In 1966, towards the end of his period in France he worked as a film extra, acting as a longshot stand-in for Jacques Tati in his film "Playtime".
  Title: Les Vacances de Monsieur Hulot
  Passage: Les Vacances de Monsieur Hulot (French: Les Vacances de M. Hulot ; released as Monsieur Hulot's Holiday in the US) is a 1953 French comedy film starring and directed by Jacques Tati.  It introduced the pipe-smoking, well-meaning but clumsy character of Monsieur Hulot, who appears in Tati's subsequent films, including "Mon Oncle" (1958), "Playtime" (1967), and "Trafic" (1971).  The film gained an international reputation for its creator when released in 1953.  The film was very successful as it had a total of 5,071,920 admissions in France.
  Title: Playtime
  Passage: Playtime (sometimes written "PlayTime" or "Play Time") is a 1967 French comedy film directed by Jacques Tati.  In "Playtime", Tati again plays Monsieur Hulot, a character who had appeared in his earlier films "Mon Oncle" and "Les Vacances de Monsieur Hulot".  As mentioned on the production documentary that accompanies the Criterion Collections DVD of the film, by 1964 Tati had grown ambivalent towards playing Hulot as a recurring central role.  Unable to dispense with the popular character altogether, Hulot appears intermittently in "Playtime", alternating between central and supporting roles.
