If you loved A Mighty Wind, try Waiting for Guffman
A bridge between a film you've already seen and one most people haven't. Here's what they share, and what the second one does that the first one doesn't.
What they share
Both films are directed by Christopher Guest, and they both carry the playful mood tag, and they sit in Comedy / Music territory. If that's the register that drew you to A Mighty Wind, the second film will land in a comparable space — through a different lens.

What Waiting for Guffman is
Christopher Guest skewers community theater, as only he can. The citizens of Blaine, Missouri put on a musical, hoping to impress a big-time Broadway producer. It's hard to say who's more deluded about their talents.
