When Paul Soter and Erik Stolhanske are initially being led to the Beerfest arena, the other members of Broken Lizard have cameos. Kevin Heffernan is a German woman putting a human leg through a meat grinder, Jay Chandrasekhar is a blind bearded man being circled by a singing boy on a tricycle, and Steve Lemme appears as a clown-like character sporting a strap-on.
"Schniedelwichsen" is a name put together from vulgar German words. The literal translation is "cock jerking".
All three of the senior Von Wolfhausens were named for classical music composers. They are named for Ludwig Von Beethoven, Johann Sebastian Bach, and Wolfgang Amadeus Mozart
The final scene with the message "Coming Soon - Potfest" was confirmed by Broken Lizard as a joke to make this film have an open-ended feel. The troupe said there has been fan support to create the sequel, which might be made as an animated film.
