A play within a film within a story within a farce, this whodunnit is a maze of silliness and murder. Set in London’s West End in the 50’s, Agatha Christie’s Mousetrap has just hit its 100th stage performance and a film deal is solidly in the works. It’s these actors, writers, directors and film folks that attend the post-performance party in appreciation for the milestone. Narrated in the words of the future film director Leo Köpernick (Adrien Brody) who is most hated by all guests in attendance and who also happens to be the victim, the scene is set for a murder most foul. Soon Inspector Stoppard (Sam Rockwell) and rookie Constable Stalker (Saoirse Ronan) are on the case and their investigation goes sideways, upside down, and backwards with bouts of insanity, slapstick, and confusing murder mystery shenanigans. In the end, we find ourselves at the Christie residence a la Clue as all are gathered to reveal the identity of the murderer.
