If you combined Michael Moore, Stephen Colbert and The Yes Men, you would come up with Denmark's Mads Brügger.
In his earlier documentary, "The Red Chapel," Brügger created a fake theater troupe to tour North Korea on a cultural exchange, and came away with astounding footage of the conditions there.
In his latest stunt documentary, "The Ambassador," Brügger actually buys his way into the diplomatic corps, and lands in the Central African Republic -- where he finds a world of corruption, partying and diamonds.
"The Ambassador" screens in the World Cinema Documentary competition of the 2012 Sundance Film Festival.
