Based on the Regex error shown on the Test Results tab, the challenge apparently doesn't like the "Movie." prefix or the spaces in the filter expression. You can change those to pass the challenge, but you might also want to report this as a bug to Support. (It might get you a "special Exterminator badge". :beetle:)
