"My Dinner with Andre" is my all-time favorite film. I watch this movie often, each time of which I notice another layer of meaning. In addition to the superior dialogue and direction in this film (which other reviewers here have aptly described), the movie is rich, visually. This movie is not visually boring, despite the fact the cameras are on Wallace Shawn and Andre Gregory for nearly two hours. Andre Gregory, especially, is such an engaging conversationalist that he evokes compelling mental images in the audience as to what these far away places might look like (i.e., the Sahara and the Polish forest to name a few). After all, Gregory said "I consider myself a bit of a Surrealist," meaning that the world of dream images in the mind's eye are the locus of true imagination. It's a superb use of the verbal to evoke the visual. Yes, the film is overtly naturalistic (i.e., the restaurant setting, a 2-hour meal with "real" characters), but the sheer dialogue transports one beyond mere verisimilitude.
Having the audience imagine, in their own ways, what these venues might look like is so contrary to what we get so often in American movies today. We typically get in your-face visuals and glitzy special effects (e.g., "Lord of the Rings) that allows no room for viewer imagination: its all artificially provided for you. Such films leave me, to use Gregory's words, "passive and impotent."
"My Dinner with Andre" respects its audience by reminding us what it is to be truly human. Having conversations as portrayed in this film is my ideal evening out with a good friend(s).
I can't recommend this movie enough.
