This review comes on the heels of having just viewed the 2017 abortion directed by and starring Kenneth Branaugh and is more a comparison of the two cinematic versions than a simple review of the 1974 Sidney Lumet version. First of all, Agatha Christie's novel takes place in the 1930s. Lumet acknowledges this is a "period piece" and treats it as such. Glamour was a big thing in films set before the end of the studio system in Hollywood, and Lumet gives us plenty of it here (Branagh gives us little). The dramatic score for Lumet's 1974 film was composed by Richard Rodney Bennett, who is also the pianist on the soundtrack, which is lushly orchestrated and fits this production quite nicely. The all-star cast here is composed of well-known, proven actors, beginning with Albert Finney as Christie's sleuth, Hercule Poirot. It's unnecessary to list the entire star-studded cast here, as it's on the main page for the film, but the whole cast gives exemplary performances. The cinematography is exquisite, with Geoffrey Unsworth's excellent use of Panavision cameras and lenses. In fact, there's nothing bad to be said about the film. This was followed by several other Brabourne-Goodwin productions of Agatha Christie novels ("Death on the Nile," and "Evil Under the Sun," both with all-star casts with Peter Ustinov as Poirot and "The Mirror Crack'd" with Angela Lansbury as Christie's female sleuth, Miss Jane Marple), but none of the successors were as well-done as this one. The Kenneth Branaugh remake tells us that Branaugh's portrayal of Poirot was more important to him than the development of any of the other characters. The viewer gets the impression that Branaugh focused more on Poirot's obsessive-compulsive side than any other characterization in his film. In one word each, here's a description of the two versions: Lumet, 1974: magnificent; Branaugh, 2017: pedestrian.
