I 400 colpi

All the young actors who unsuccessfully auditioned for the role of Antoine were used in the classroom scenes.

(at around 1h 39 mins) At the end, right as Antoine reaches the water's edge, the shadows of the crew can be seen on the sand and water.

The Spanish (Spain) dubbed version of this film has about 12 minutes of footage missing. When Antoine's mom returns home and argues with her husband while Antoine pretends to sleep, the scene in which the family heads home after going to the movie theater, when Antoine and René smoke and drink in Rene's room and when they throw things from the ceiling with blow pipes, are among the scenes that are missing. The scene in which the father talks about the new secretary sleeping with the boss is dubbed to the father speaking about the boss liking the new secretary and her being a very good worker and being promoted because of that. The interview with the psychologist was dubbed with the psychologist asking Antoine if he has had a girlfriend, and he talks about dating some girls but not liking any of them and finding a girl he liked but who chose an older guy instead of him, when in the original, he is asked if he's slept with a woman and he goes on to talk about when he tried to get one to sleep with.
