The unauthorized use of the Louis Vuitton trademark and use in the movie "The Hangover Part II" of a knockoff bag led french maison Louis Vuitton to file a lawsuit against Warner Bros. The suit was filed in a New York federal court on December 22, 2011.
According to LV, instead of sourcing a real Louis Vuitton bag, producers apparently utilized a knock-off made by the Diophy group of companies, who LV is also suing to prevent it selling its goods in the US.
The "Louis Vuitton" bag appears in the airport scene of the movie, where Zach Galifianakis's character "Alan" travels with a bag stamped with "LVM" and warns "Stu": "Careful, that is ... that is a Louis Vuitton." As claimed by LV, this scene can cause "consumer confusion" and consequently, harm the brand.
LV claims trademark dilution, false designation of origin and unfair competition. The french house asks for profits from the film and triple damages, the destruction all copies of movie along with promotional materials that include the scene in question and an injunction prohibiting WB from distributing the "The Hangover Part II" as long as the bag in question appears in the movie.
