Rose (Binoche) is a beautician, glamorous at first glance but, upon closer inspection, wearing way too much makeup and clothes that fit a little too snuggly. She has a forthright manner and lousy taste in men. She is at the airport in an attempt to run away from her latest abusive boyfriend (a cameo by Sergi Lopez). Felix (Reno) is a neurotic, finicky claustrophobic, a former chef turned frozen food king whose track record with the opposite sex is as bad as Rose's.
The two meet when Rose asks to borrow Felix's cell phone after inadvertently flushing her own down the toilet. As problems mount at the airport, they find themselves continually running into each other. Not the sociable type, especially toward someone with Rose's working-class roots, Felix deflects her attempts to engage him in conversation, then feels guilty and suggests she hole up in his room at the airport hotel until flights resume.
Needless to say, the two are polar opposites, and their attempt at getting along, even for just one evening, seems doomed. But what would a romantic comedy be without obstacles?
The film is essentially a two-hander. Aside from the setup, it focuses exclusively on two characters who appear together on-screen for pretty much the rest of the picture.
Jet Lag, directed and cowritten by Danièle Thompson (screenwriter of Cousin, Cousine and La Bûche), along with her son Christopher, contains convincing comic dialogue, well-delivered by the two stars. And considering its limited locales, the film never feels stagy. But the two characters aren't particularly interesting or engaging, and the audience never feels that they are meant to be together. The problem may partially be that neither actor fits his/her character.
Early on, Rose reveals that she would love a "whole day when my life would be like an American movie." She envisages Roman Holiday, the film she is watching at the start of the picture. Unfortunately, Jet Lag has none of that film's winsome charm. When you have such wonderfully iconoclastic stars at your disposal, the last thing you should do is ask them to take cookie-cutter roles.
