A Mighty Wind

This is the fourth showbiz-schmucks mockumentary from Christopher Guest and his Spinal Tap/Guffman/Best in Show troupe, and if we’re lucky they’ll be able to go all the way to eleven. This time around the target is folk music—lampooning the malcontents, losers, and loonies reunited decades past their prime for a Carnegie Hall memorial concert. The most promising news: For the first time since This Is Spinal Tap, Guest reunites with bandmates Michael McKean and Harry Shearer in the guise of a Kingston Trio send-up called the Folksmen. The songs we’ve heard so far are a credit to the legacy of “Big Bottom.” Folk’s tendencies toward pomposity and overearnestness make spoofing it practically the definition of shooting fish in a barrel, but you know what they say: Hear “If I Had A Hammer” once too often, and everything starts looking like a nail.
