These days most comedy directors would consider themselves fortunate to attract, and be able to afford, the combined talents of Bradley Cooper, Paul Rudd, Amy Poehler, and Elizabeth Banks. Back in the spring of 2000, first-time filmmaker David Wain not only hired those actors for his anarchic summer-camp spoof Wet Hot American Summer, but he got away with paying practically nothing for the film’s massive cast, which also included Janeane Garofalo, David Hyde Pierce, Molly Shannon, and Christopher Meloni.
