Then, off the to-watch shelf, I pulled EVIL UNDER THE SUN. No, not the marvelously entertaining Peter Ustinov version with Maggie Smith, Diana Rigg, Roddy McDowall, James Mason, and others.
No, this was the BBC "official" version with David Suchet. It looked wonderful despite ita 4:3 dimensions and mono sound, and while the story is of course the same of the 1982 film adapted from the Christie book, the characters are truer to the original story so the Brewster character was a woman and not Roddy McDowall (although he played it like Tallulah Bankhead so it's hard to tell what sex he was trying to represent). The James Mason character was also originally a woman. And there was heroin smuggling in the story which was not at all in the 1982 film.
Still, the denouement was the same, same guilty party (parties) and same method of murder.
