If you're fan of the grand dame of murder mysteries, Agatha Christie, the upcoming remake of her 1934 novel Murder on the Orient Express will already be on your must-watch list, but if you don't know her work this trailer will make you want to get familiar fast.

An incredible all-star cast has been assembled for the remake including Johnny Depp, Kenneth Branagh, Michelle Pfeiffer, Star Wars' Daisy Ridley, Penélope Cruz, Beauty and the Beast's Josh Gad and Oscar-winner Judi Dench. And let's be honest, who doesn't love watching a mystery being solved?

The sumptuous film takes place on the luxe Orient Express train and the decadent costumes alone make it well worth the ticket price. Then there's the matter of Kenneth Branagh's moustache... Branagh directs and takes on the iconic role of humble Hercule Poirot 'The greatest detective in the world' (according to him) with style and panache and sporting a mo the envy of all 'Mo for Movember' gents around the world - whether it's the work of an amazing hair and make-up team or is his own hair, it's compelling either way.

This second trailer teases Ratchet (the gangster played by Johnny Depp) as the murder victim with every single passenger on the train a suspect. Whodunnit? We'll have to wait until November to find out, but until then watch the spectacular second trailer here:

Murder on the Orient Express will be in cinemas on November 11, 2017.
