This is the 1974 version, not the Kenneth Branagh handlebar mustache version. Unfortunately, I watched this knowing the ending (spoiled by a "host a murder" game I played when I was a teenager). I don't think that really matters much because, as with most of these types of murder mysteries, all necessary clues are not really revealed to the audience. The point is to get to know the suspects' quirks and then wait to have Poirot tell the story of what really happened. Nonetheless, it was an entertaining, star-studded affair and I enjoyed Albert Finney's Poirot.
