Anvil! The Story of Anvil
You spend the first half of this hilarious, engrossing documentary wondering whether to believe the story of Robb and Lipps, best friends and partners in the long-running metal band Anvil. The two middle-aged rockers work 9-5 jobs, scraping together just enough cash for one big tour, and Stonehenge-sized disasters ensue. But by the end of the movie, you want to see their band thrive almost as much as they do. The final scene may make you bawl your eyes out even while you bang your head.
