The Hangover Part II is beginning to seem like a litigation magnet. The latest lawsuit was filed last week in federal court in Los Angeles according to Entertainment Weekly. It alleges that filmmakers mimicked a script that aspiring scribe Michael Alan Rubin based on his own marital misadventures in Asia. Plaintiff Rubin claims The Hangover II “is copied from the treatment … and also from the real life incident of the Plaintiff, because the protagonist … travels from the United States to an Asian country to marry his Asian girlfriend.” How did they get his script, you might wonder? Rubin claims his ex-wife gave the filmmakers his story, and furthermore accuses them of defaming him with descriptions of Ed Helms’ character’s drug-fueled antics including sex with a transsexual prostitute. Rubin is representing himself. Back when The Hangover became a hit in summer 2009, you may recall, Deadline revealed that the original movie was loosely based on the Las Vegas escapades of producer Tripp Vinson. Meanwhile, a previous lawsuit filed by the tattoo artist who designed the ink adorning Mike Tyson was settled, and another filed by a stunt man injured during the making of the film is pending.
