Johnny Depp was ''staggered'' by the beauty of thriller 'Murder on the Orient Express'.

The 54-year-old actor stars as Edward Ratchett in the new Sir Kenneth Branagh adaptation of the popular Agatha Christie whodunit novel of the same name, and Depp was so impressed with the British filmmaker that he would work with him again in a heartbeat.

Speaking at the world premiere of the movie at The Royal Albert Hall, in London, on Thursday (02.11.17), Depp said: ''I was staggered by the beauty of the film. Just seeing every piece of the puzzle come together in the beautiful way that Kenneth constructed the film. He's a force to be reckoned with, a genius. I'd film anything he wanted to film with me.''

'Murder on the Orient Express' follows Belgian detective Hercule Poirot who finds himself wrapped in a murder mystery after a passenger is murdered during the lavish trip through Europe.

The film sees Branagh portray Poirot and features an all-star cast including Dame Judi Dench, Michelle Pfeiffer, Daisy Ridley, Josh Gad, Penelope Cruz and Willem Dafoe.

Although the film has a number of Hollywood greats, Depp admitted Dench was his favourite co-star to work with.

He gushed: ''Judi Dench is my one true love. She levitates.''

Depp's co-star and 'Frozen' actor Gad, 36, admitted the whole cast bonded together and was a ''love fest''.

He said: ''When you first get there you are concerned about how all those personalities are going to mesh but it was love fest.

''Every day when we were done shooting we would all go and get drinks or something. There was this incredible game Penelope Cruz introduced us to called Werewolf, where you all sit around as a group and two people are, without knowing it, werewolves - and you have to determine who they are.

''Penelope and Javier Bardem [husband] have been playing this game for years. We played it the whole time.''
