Beerfest is a 2006 American comedy film directed by Jay Chandrasekhar and written by the comedy group Broken Lizard (Chandrasekhar, Kevin Heffernan, Steve Lemme, Paul Soter, and Erik Stolhanske), who also star in the film alongside Nat Faxon, Will Forte, Ralf Möller, Mo'Nique, Eric Christian Olsen, Jürgen Prochnow, Cloris Leachman, and Donald Sutherland.

At the funeral of their German-born grandfather Johann von Wolfhausen, half-wit brothers Jan and Todd Wolfhouse discover that family tradition demands that they travel to Munich at Oktoberfest to spread his cremated ashes at the Theresienwiese.

They then get led to the location of and participate in Beerfest, an underground drinking game tournament run by Baron Wolfgang von Wolfhausen, after discovering that the von Wolfhausens are related to the Wolfhouses, with the German team angrily denying the family ties, revealing that Johann was a stable boy who stole the recipe for "ze greatest beer in all ze world" decades ago and ran away with his prostitute mother (the brothers' great grandmother), Great Gam Gam and then killing the man who brought them.

Swearing to get revenge on the Germans, Jan and Todd return to Colorado where they recruit their drinking friends from college—binge drinker Phil "Landfill" Krundle, Jewish scientist Charlie "Fink" Finklestein, and male prostitute Barry Badrinath—to assemble an American Beerfest team, though they do not divulge this to Great Gam Gam.

Barry explains that he cannot join due to a traumatizing incident years ago during a game of table tennis, in which the big end of a racket was forcefully shoved up his anus.

The Americans are allowed to participate after Jan and Todd show how uncannily they resemble the two Beerfest founders, thus convincing the crowd of their von Wolfhausen ancestry.

When asked about where the concept for the film came from, Jay Chandrasekhar said "We were at a Beer garden in Australia (wearing our police uniforms) and we went on stage and challenged the top five drinkers in the room to a chug off.

The website's critical consensus reads, "Beerfest features some laugh-inducing gags, but is too long and the pacing too uneven to form a coherent, functioning comedy.

[10] David Jenkins in Time Out magazine wrote it "appears to have been conceived on the back of a beermat and its trashy direction, nonexistent plot and dismal comic mugging would seem to suggest that preparations progressed no further".

[11] Jeannette Catsoulis of The New York Times disagreed: "Best viewed while sloshed, Beerfest is idiotic, tasteless and irrepressibly good-natured in other words, a frat-house classic".
