One of the year's most enjoyable films, Robert Altman's A Prairie Home Companion is about the fictitious last performance of Garrison Keillor's enormously popular radio program. Funny, emotionally moving, and, above all, gloriously tuneful, A Prairie Home Companion celebrates the American values that have taken a beating in the last few years. A gentle, lovely celebration from a genuinely great director. I've never seen actors in any movie who seemed to be enjoying themselves more. Listening to Meryl Streep and Lily Tomlin harmonize, one is tempted to think longingly of the music careers that might have been.
