When a murder occurs on the train on which he's traveling, celebrated detective Hercule Poirot is recruited to solve the case.
 
This is Kenneth Branagh’s 1st appearance as Hercule Poirot.
 
ALL ABOARD!...for murder.
 
FUN FACT:  When the trailer was first released, many Agatha Christie fans complained about Kenneth Branagh's interpretation of Poirot's iconic mustache.  Apparently, Kenneth Branagh was aware of the over-extravagance of his character's mustache, but he justified it by the fact that there were fifteen quotes in the original novel mentioning the mustache. When the book 'Murder on the Orient Express' was first adapted for the screen in 1974, Christie, who was still alive at the time, was reportedly unhappy with Albert Finney's Poirot's mustache.
