Romain Duris in Christophe Honoré's "Dans Paris"

For a character who is depressive, uninterested in communication, and spends most of the movie firmly planted in bed, Romain Duris manages to surprise with such buoyantly poignant moments like this.

P.S. There's a short film starring Louis Garrel and a band of American tourists on the special features of the DVD that is worth watching for any film snob.
