A Mighty Wind is a 2003 mockumentary about a folk music reunion concert in which three folk bands must reunite for a television performance for the first time in decades. It was directed by Christopher Guest. The film is thought to reference the 2003 tribute concert to folk music producer Harold Leventhal that reunited several of the folk groups that Leventhal had managed. Guest co-stars and utilizes his company of actors from previous films such as This Is Spinal Tap, Waiting for Guffman, and Best in Show for this film. They include Eugene Levy, Catherine O'Hara, Michael McKean, Harry Shearer, Fred Willard, Bob Balaban, Ed Begley, Jr., Jennifer Coolidge, Paul Dooley, John Michael Higgins, Michael Hitchcock, Rachael Harris, Don Lake, Jane Lynch, Larry Miller, Jim Piddock, Deborah Theaker, and Parker Posey. Several characters in the film originated in a sketch written by Guest for Saturday Night Live in 1984. A song composed for the film by McKean and wife Annette O'Toole was nominated for an Academy Award. Every song featured in the film was also written by the cast or Guest's long-term musical collaborator C J Vanston.
