It's a very good joke.
Problem is, almost all the rest of the movie that contains it is at best frustrating, often boring.
So if I tell the joke, you don't have to see the movie. This is the new film by Wem Wenders, the German who made the interesting Paris, Texas and the deeply affecting and spiritual Wings of Desire . Before the joke sequence, we meet Max at his chilly, aggressively modernist house on the ocean. He prefers to do business poolside via telephone, cellphone, e-mail and fax. He even monitors the progress on his pictures this way, watching the dailies via videophone.
