Lucky Pierre (; also known as I'm Losing My Temper) is a 1974 French comedy film written and directed by Claude Zidi, starring Pierre Richard and Jane Birkin.
Pierre Durois is a mathematics teacher at an all-girls high school in Aix-en-Provence. He also works as a ghostwriter for his father the mayor, who is seeking re-election, and for his friend who works for a tabloid newspaper.
When Pierre's students switch the contents of his folders as a joke, a speech for the mayor, an article on Jackie Logan, a famous Hollywood actress, and his students' papers all end up in the wrong hands.
Pierre finds himself on a film set trying to resolve the mix-up, and ends up spending the night at Jackie Logan's house. The tabloids catch wind, and the next day's headlines provoke dismay for the mayor and for Pierre's fiancée.
