A tattoo artist did a tribal tattoo over Mike Tyson's left eye. Warner Brothers copied the design in the movie Hangover 2. Tattoo artist is suing Warner, claiming copyright infringement. Warner is claiming fair use. To further complicate matters, Tyson is in the movie.
It's a weird case, I just like a major movie house getting nailed for something they sue other people for.
