 In 1970 he had a cameo in François Truffaut's "Bed and Board", playing the character of Monsieur Hulot, made famous by Tati.
Trafic ("Traffic") is a 1971 Italian-French comedy film directed by Jacques Tati.
 "Trafic" was the last film to feature Tati's famous character of Monsieur Hulot, and followed the vein of earlier Tati films that lampooned modern society.
Jacques Tati (] ; born Jacques Tatischeff, ] ; 9 October 1907 – 5 November 1982) was a French filmmaker, actor, and screenwriter.
 Throughout his long career, he worked as a comic actor, writer, and director.
 In a poll conducted by "Entertainment Weekly" of the Greatest Movie Directors, Tati was voted the 46th greatest of all time.
 With only six feature-length films to his credit as director, he directed fewer films than any other director on this list of 50.

"School for Postmen" (French: L'École des facteurs ) is a 1947 French short comedy film directed by Jacques Tati.

 He replicated most of the action here in his first major feature film, "Jour de fête", released two years later.
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.
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.
Mon Oncle (] ; My Uncle) is a 1958 comedy film by French filmmaker Jacques Tati.
 The first of Tati's films to be released in colour, "Mon Oncle" won the Academy Award for Best Foreign Language Film, a Special Prize at the 1958 Cannes Film Festival, and the New York Film Critics Circle Award for Best Foreign Language Film, receiving more honors than any of Tati's other cinematic works.
Parade is a French comedy film and was the final film directed by Jacques Tati.

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.
