DuJour was the fictional boy band in the 2001 film Josie and the Pussycats.
In the film, DuJour is a successful manufactured pop group whose members cross paths with the title band. The group consists of fictional performers portrayed by Donald Faison, Alexander Martin, Paulo Costanzo, and the musician Seth Green. Their exaggerated image and choreography parody the polished boy-band culture of the late 1990s and early 2000s.
Josie and the Pussycats was directed by Harry Elfont and Deborah Kaplan and released in 2001. The story follows an all-female rock band that is recruited by a powerful music company and drawn into a conspiracy involving subliminal messages in pop music.
DuJour is often confused with the film’s real central band, Josie and the Pussycats. The question asks for the fictional male pop group within the film, not the title trio.
