Voted as Roger Ebert's favorite movie of 1976, although he later expressed regret that he didn't give it to Taxi Driver (1976) instead.
The literal translation of the title is "Pocket Money," which was already the name of another film (Pocket Money (1972)). It was Steven Spielberg who suggested "Small Change." Spielberg, of course, directed Truffaut in Close Encounters of the Third Kind (1977), and made his own films about childhood adventures, E.T. the Extra-Terrestrial (1982) and The Goonies (1985).
Watching the 1976 French movie "L'Argent de Poche" on the 2004 MGM PAL DVD using the English subtitles, at (0:10:20), the teacher called on Brouillard to recite lines of a play, but there is no Brouillard role in the cast list. Switching to the French subtitles and watching the scene again, showed the name in the subtitles is Rouillard, which is a role in the cast list. Some sources note that Truffaut did not follow a standard scrip because he wanted flexibility to improvise. This would explain why so many of the children's names are used for the roles they portray. It could also explain why the translators "translate" the names of the characters.
