The brothers Aaron and Matthew Benay sued Warner Bros Entertainment Inc. and other companies for copyright infringement over their screenplay for The Last Samurai. The district court found for the defendants, but the Ninth Circuit Court of Appeals reversed on the copyright and breach of contract claims. The case discussed whether the screenplays were substantially similar through an "extrinsic test" of elements like plot and themes. In the end, the court found the screenplays were not similar enough to find copyright infringement and awarded damages to the Benay brothers.
