I watched this movie a looong time ago, but never got around to posting the review. From what I recall, it features a train (The Orient Express), a set of unique, mostly rich and interesting characters (among them Sean Connery... and Ingrid Bergman!), fantastic locales - though mostly the inside of the train - and as for the plot, it's about a murder.
In 1935, when his train is stopped by deep snow, detective Hercule Poirot is called on to solve a murder that occurred in his car the night before.
The characters, the clues, the subtle progression of what you'd nowadays consider somewhat generic, but might've been innovative and new back then, provides a classy detective drama from a different time, and even if things do move slow they were never boring. There's always something to see or something being said, plenty of reasonable deductions and plenty of strong personalities, one with a murderous intent. It's a classic!
