Albert Finney as Hercule Poirot in "Murder on the Orient Express" (1974). Our second "Murder on the Orient Express" (the first was made in 2010) -- one more to go.
Set in 1935. Basically the same story as the first version we viewed (noted above). But, with a couple notable differences. I assume this one was closer to the Agatha Christie original story. The 2010 version we watched (noted above) may have been slightly better. But, each had its pluses and minuses. In this version, Poirot was also a "deformed overweight person" -- perhaps deformed too much to be real (lacking a "back story" to explain it).
Interestingly, the "set" for this movie was the "actual Orient Express" luxury train which was still functional in 1974. Also interesting to me (who does not pay attention to who is acting), I recognized the names of several of the actors.
