What a gem.  If you liked Knives Out, Clue, and Murder By Death, this is the movie for you!  The story takes place in 1950’s London.  In the story, some producers have decided to make a movie version of Agatha Christie’s play ‘The Mouse Trap’ (which is still running in London after more than 50 years, by the way).  The cast of characters include a despised director ( Adrian Brody), a rookie constable (Saoirse Ronan, as an innocent appearing but smarter-than-you-thought PC Stalker, the rookie detective who  steals the show!) and an alcoholic world weary detective (Sam Rockwell).  The movie has to be delayed when a member of the cast is murdered!  Some of my favorite suspects included Shirley Henderson (remember her as Moaning Myrtle in the Harry Potter series?), David Oyelowo and Ruth Wilson.  This is all very tongue-in-cheek and includes puns, play on words, literary allusions and the breaking of the fourth wall.  I also enjoyed the references to 50’s movies.  One highlight is an appearance by Agatha Christie herself and a trippy take on the old mystery trope “The butler did it.”  This is another movie that won’t be around in theatres long , so if you want to see it in a theatre, stop reading this review and get going!  You will be glad you did!
