Jean-Philippe is a French comedy film that was released in 2006. The film tells the story of Fabrice Valentine (played by Fabrice Luchini), a middle-aged office worker who is obsessed with the music of French rock star Johnny Hallyday. He spends his days listening to Hallyday's music, collecting memorabilia, and dreaming of meeting his idol.
One day, Fabrice wakes up in an alternate universe where Johnny Hallyday never existed. He is shocked and confused, but determined to find a way to bring Hallyday back to life. He discovers that in this universe, he has a doppelganger named Jean-Philippe Smet (also played by Johnny Hallyday), who is a small-time insurance salesman.
Fabrice travels to Hallyday's hometown of London to see if he can find a way to convince Jean-Philippe to become Johnny Hallyday. His efforts are initially met with resistance, but as he spends more time with Jean-Philippe, he begins to understand the pressures and challenges of fame and celebrity.
The film is a lighthearted satire on the cult of celebrity and the allure of fame. It also explores themes of identity, purpose, and the meaning of success. The performances by Luchini and Hallyday are praised for their humor and warmth, and the film's soundtrack features many of Hallyday's classic songs.
