Screenwriter Michael Alan Rubin is suing the team behind The Hangover Part II (including Warner Bros.) for copyright infringement, defamation, and fraud, among other things. Rubin says the movie is a rip-off of a script he wrote about his “wild personal experiences in Asia,†which apparently took place after he and his then-wife, Tamayo Otsuki, broke up on their honeymoon. (He blames his now ex-wife for showing the treatment to the filmmakers.) The “defamation†aspect of the suit has something to do with the franchise’s portrayal of Ed Helms’s character, who — in case you forgot — is a big nerd with a tendency to get himself into trouble with prostitutes. Sorry, Michael, but you can’t have it both ways. [THR]
