Martin Sheen is a personal friend of the director, hence his cameo in the film. It is disappointing that this talented actor's appearance lent nothing more than pasta-eating to this film, but that is more a fault of the script than of Mr. Sheen's. Apparently, my answer is not long enough to fit the minimum, so I will also say this -- this is a movie with much better characters than the movie deserves, the two lead performers do a fine job with the slight material, and everything else about the film is a mild disappointment. I say "mild" because there is nothing to get terribly excited about in the film, positively or negatively.
