Most of the film is presented in a 1:1 aspect ratio, where the "viewing area" of the screen is a perfect square.
When Diane, Steve, and Kyla are having dinner, Steve tells a story about how when he was little and his parents didn't want him to understand their conversations, they would speak in English. Steve says that most conversations ended with either "shut up" or "f*** off." He then says that he tried to befriend a little girl who spoke English by telling her to "shut up" and "f*** off," because those were the only English phrases he knew, and he didn't know what that meant. In the DVD commentary, Anne Dorval actually admits that this is her own personal experience from when she was little, and that she told a neighborhood child to "shut up." Xavier Dolan thought her story was funny and decided to put it into the movie.
Received a 12 minute standing ovation at the Cannes film festival.
The song Wonderwall starts immediately after Steve coughs in a scene. On the Oasis album (What's The Story) Morning Glory, a cough precedes the intro to Wonderwall as well.
