Murder on the Orient Express is a 2017 American mystery drama film directed by Kenneth Branagh with a screenplay by Michael Green, based on the 1934 novel of the same name by Agatha Christie. The film stars Branagh as Hercule Poirot, with Penélope Cruz, Willem Dafoe, Judi Dench, Johnny Depp, Josh Gad, Derek Jacobi, Leslie Odom Jr., Michelle Pfeiffer, and Daisy Ridley in supporting roles. The film is the fourth adaptation of Christie's novel, following the 1974 film, a 2001 TV film version, and a 2010 episode of the television series Agatha Christie's Poirot. The plot follows Poirot, a world-renowned detective, as he seeks to solve a murder on the famous trans-European train in the 1930s.
Principal photography began in November 2016 in the United Kingdom; it is one of the few productions in recent decades to use 65mm film cameras. Murder on the Orient Express had its world premiere on November 2, 2017 at Royal Albert Hall in London, and was theatrically released in the United States on November 10, 2017, by 20th Century Fox. The film has grossed over $349 million worldwide and received mixed reviews from critics, with praise for the cast's performances and the production value, but criticism for not adding anything new to previous adaptations.
