The Hangover 2 just can't catch a break. After running into some issues a few months ago because of a trademarked tattoo featured in the film, Warner Bros. is facing legal trouble again - this time from Louis Vuitton, who's pretty pissed that the film is using fake luggage and claiming that it's real. Can't we all just get along?

The luggage used in the film was made by the Diophy group, a company that Louis Vuitton is also suing to prevent them from selling their goods in the US. From the Guardian, "A trademark suit against Warner Bros, which was filed yesterday in a New York federal court, suggests the firm has been damaged after Galifianakis's line, "careful, that is a Louis Vuitton", became a catchphrase ... In short, the company claims trademark dilution, false designation of origin and unfair competition."

Ultimately, Louis Vuitton wants Warner Bros. to alter the luggage in the DVD. Fair enough, but who is actually going around and saying, "careful, that is a Louis Vuitton"? When did that become a catchphrase?
