When discussing three of the films in which Christopher Guest has been centrally involved thus far (i.e. Waiting for Guffman, Best in Show, and A Mighty Wind), it would be inaccurate to suggest that they follow the same formula. Rather, Guest is guided by an equation which consists of the following: an ensemble company of immensely talented actors, hilarious satirical material presented in a "mockumentary" style, and a multi-dimensional plot which concludes with a Grand Event. He directed the three films and plays a central role in them, as does Eugene Levy with whom Guest also co-authored the screenplay for each. Best in Show remains my personal favorite but A Mighty Wind is nonetheless immensely entertaining even as it (oh so subtly) suggests some serious issues along the way.
Briefly, here is the situation. Jonathan Steinbloom (Bob Balaban) is the son of a legendary producer of folk concerts in the 1950s and 1960s. In loving and respectful memory of his father, Steinbloom decides to produce a reunion concert in New York City's Town Hall which would bring together again Mitch & Mickey (Levy and Catherine O'Hara), The Folkmen (Guest, Michael McKean, and Harry Shearer) and the eight members of The New Main Street Singers. Once married, Mitch Cohen and Mickey Devlin are now divorced; when the film begins, she is now married to Leonard Crabbe (Jim Piddock). All of the performers eventually agree to appear and begin to prepare somewhat apprehensively for the concert. Of course, there are the inevitable tensions and pressures as they do so, exacerbated by the emotional baggage which several (notably Mitch & Mickey) have been dragging along in their lives for so many years. The concert finally begins and then....
Others have their own reasons for admiring this film so much. Here are three of mine. First, the most effective "mockumentaries" have a high level of verisimilitude. In this instance, if you had no idea that it is the score from A Mighty Wind, and were already familiar with various folk music groups, you would believe that selections such as "Old Joe's Place" and "Never Did No Wanderin'" are authentic. Guest and his associates took great care to ensure that the score is at least comparable with classics once performed by, for example, Dick & Dee Dee ("The Mountain's High," "Tell Me," "Young And In Love," "Love Is A Once In A Lifetime Thing," and "Where Did The Good Times Go." Now consider the titles of the songs which Mitch & Mickey sing in A Mighty Wind: "When You're Next To Me," "One More Time," "The Ballad Of Bobby And June," and "A Kiss At The End Of The Rainbow." The Folkmen and The New Main Street Singers also have their historical counterparts which other reviewers have duly noted.
The second reason is that all of the acting is first-rate. Fred Willard (as talent agent Mike LaFontaine) and Jennifer Coolidge (as PR specialist Amber Cole) are especially noteworthy. It is quite an achievement to cast so many from Best in Show in roles in this film which are wholly dissimilar. It is an even greater achievement for the actors to bring it off. To name but two, Jane Lynch (Laurie Bohner) and John Michael Higgins (Terry Bohner).
Finally, probably because I attended so many concerts 35-40 years ago and collected an even greater number of the folk music albums, A Mighty Wind evokes an abundance of pleasant memories for me, memories of an age and of a society which now seem so far away. In my opinion, this is a much more serious film than are Waiting for Guffman and Best in Show. With all due respect to the effectiveness of the comic elements, there is poignance in the awkwardness between Mitch & Mickey even as they seem to reach some degree of closure when singing "A Kiss At The End Of The Rainbow." It is no fault of Guest, his cast, and crew that many such as I who enjoy seeing this film will later reflect on what awaited us at the end of our own "rainbow."
