Johnny Depp and Star Wars' Daisy Ridley are to star in a new film adaptation of Agatha Christie's acclaimed mystery Murder On The Orient Express.

The film is being directed by Kenneth Branagh, who will also star as Christie's iconic detective Hercule Poirot. Depp will play Ratchett and Ridley has been cast as Mary Debenham.

The film's impressive ensemble cast will also include Judi Dench as Princess Dragomiroff, Michelle Pfeiffer as Mrs Hubbard, Michael Pe?a as Marquez, Derek Jacobi as Masterman and Hamilton's Leslie Odom Jr. as Doctor Arbuthnot.

Meanwhile, Lucy Boynton will play Countess Andrenyi and Tom Bateman will appear as Bouc. Twentieth Century Fox announced this evening (September 29) that shooting will start in London in November, but added that "there are still a few key roles left to cast".

Branagh said in a press release: "Christie's Murder is mysterious, compelling and unsettling. I'm honoured to have this fantastic group of actors bring these dark materials to life for a new audience."

Christie's novel, first published in 1934, has already been adapted for film, TV and radio on several occasions over the years, most notably as an acclaimed 1974 movie starring Albert Finney, Ingrid Bergman, Sean Connery and Lauren Bacall.
