Murder on the Orient Express: Agatha Christie´s classic

The fifth film adaptation of  Murder on the Orient Express – the most famous novel by Agatha Christie – has  been released recently. If you love whodunnits and if you love Agatha Christie´s stories, you are bound to watch the latest adaptation of  A. Christie´s classic. This film has been directed by Kenneth Branagh who also plays the role of the Belgian detective Hercule Poirot. I have posted the official trailer for the film as well as the trailer for the 1974 film adaptation so that you can compare both versions.

Just by having a look at both trailers, what conclusions can you draw? What do both films have in common? As we are dealing with crime stories and suspense, what kind of elements  should a good trailer include to awaken people´s interest?
