Jet Lag (French: Décalage Horaire) is a 2002 French romantic comedy film starring Juliette Binoche and Jean Reno. It is the second film directed by Danièle Thompson, following Season's Beatings (1999).

At Charles de Gaulle Airport in Paris, a French beautician (Juliette Binoche) on her way to a new job in Mexico accidentally meets a French chef (Jean Reno) who has been delayed on his way to Germany from his residence in the United States. Labor strikes, bad weather, and pure luck cause the two of them to share a room overnight at the airport Hilton hotel. Their initial mutual indifference and downright hostility evolves into romance and a re-examination of their lives.

Danièle Thompson originally wrote the script for Miramax Films in the early 1990s with Isabelle Adjani attached to star in an English-language version.

Thompson obtained permission to film at Charles de Gaulle Airport in Paris prior to September 11, 2001. After the terrorist attacks, permission was withdrawn. Thompson then obtained permission to use Lourdes Airport, but was not convinced that viewers would believe it was Charles de Gaulle. Eventually she managed to gain 10 shooting days access to Paris. The rest was filmed on sets and in Libby Airport.

Décalage Horaire is the second collaboration of mother and son writing team Danièle Thompson & Christophe Thompson after the 1999 film La Bûche.

Décalage Horaire is one of the rare comedies in Juliette Binoche's career, after Les Nanas' (1985) A Couch in New York (1995) and Chocolat (2000).
