Yvan (Yvan Attal) is a sports journalist in Paris who is married to Charlotte (Charlotte Gainsbourg), a famous screen actress. Everywhere they go fans surround her, asking for autographs. Yvan, who doesn't have much patience, is especially peeved by the way his wife can book a table at a restaurant after he's been advised to check elsewhere because the place is filled. He is really irked when a stranger asks him if it doesn't bother him to watch Charlotte have sex on screen with another man. The fellow admits that he's certainly been aroused watching her.

In an essay on love and virtue, Havelock Ellis writes: "Jealousy is a dragon that slays love under the pretense of keeping it alive." Yvan allows this question put to him by a person he doesn't even know to undermine his intimate relationship with Charlotte as she heads off to London where she will be starring opposite John (Terence Stamp), a handsome and charming actor known as a lothario. When she arrives on the set, the French actress learns from the authoritarian director (Keith Allen) that she is slated to do a nude love scene. Charlotte tells him that she doesn't feel comfortable doing this. When he refuses to budge, she says she'll only do the scene if all the crew take off their clothes as well. Much to her surprise, the director agrees. Naturally, Yvan arrives on the set and is shocked to see what is going on. His jealous over-reaction creates a rift with Charlotte and almost sends her into the arms of John.

Yvan Attal directs this French romantic comedy with a light touch and makes the most of the wacky ways in which the sports journalist tries to cope with his pestering moods of jealousy. He even joins an amateur acting troupe to experience for himself what it is like to perform in front of others. A sidebar vignette involves the marital strife in the lives of his pregnant Jewish sister (Noemie Lvovsky) and her weak-willed husband (Laurant Bateau) who are squabbling over whether or not to have their unborn son circumcised.

Fans of Roger Michell's film Notting Hill will also enjoy this diverting drama which covers some of the same distinctive challenges of trying to maintain a romantic relationship with a celebrity.
