Description: Director Robert Altman and writer Garrison Keillor join forces with an all-star cast to create a comic backstage fable, "A Prairie Home Companion," about a fictitious radio variety show that has managed to survive in the age of television. On a rainy Saturday night in St. Paul, Minn., fans file into the Fitzgerald Theater to see "A Prairie Home Companion," a staple of radio station WLT, not knowing that WLT has been sold to a Texas conglomerate and that tonight's show will be the last. Shot entirely in the Fitzgerald, except for the opening and closing scenes which take place in a nearby diner, the picture combines Altman's cinematic style and intelligence and love of improvisation and Keillor's songs and storytelling to create a fictional counterpart to the actual "A Prairie Home Companion" radio show, which has heard on public radio stations coast to coast for the past quarter-century (and which, in real life, continues to broadcast). The result is a compact tale with a series of extraordinary acting turns.
