Peter Debruge Chief Film Critic Twenty years ago, I was fortunate enough to visit the set of “Team America: World Police,” an ambitious Jerry Bruckheimer-style action parody, starring puppets, for which Trey Parker and Matt Stone had constructed an enormous North Korean set out of cocktail umbrellas and take-out containers. Driven by equal parts obstinacy and nostalgia (for the vintage “Thunderbirds” TV show), it was the craziest thing the “South Park” creators had ever done.
