The Hangover Part II” is at the center of yet another lawsuit, this time by high-end designer Louis Vuitton, the Hollywood Reporter reports.

In a scene from the film, a sequel to the 2009 hit comedy about a wacky Las Vegas bachelor party, Zach Galifianakis’s character, Alan, scolds Stu (Ed Helms) for throwing a piece of his luggage.

“Careful, that’s a Louis — that is a Louis Vuitton,” Alan says.

Allegedly it wasn’t. The bag was a knock-off, according to the suit filed in a New York federal court Thursday, and now Louis Vuitton is suing Warner Bros. for trademark dilution, false designation of origin and unfair competition. The company claims the public will confuse the fake bag for the real thing, thus harming the brand.

Louis Vuitton asked Warner Bros. to remove the scene from the DVD months before it was released, to no avail, according to the suit (posted by Paid Content). The company wants the studio to destroy any materials that include the scene, and is asking for a share of the profits and damages.

The studio was also sued by the tattoo artist who created Mike Tyson’s tribal face piece after a similar design was used in “The Hangover Part II.” That suit was settled amicably under undisclosed terms this summer.

Warner Bros. declined to comment on the suit when contacted via e-mail by Celebritology.
