The Mirror Crack’d is a solid, unsurprising Christie adaptation, when all is said and done. Angela Lansbury’s sole turn as Miss Marple adapts perhaps the most Hollywood friendly Marple story, with its focus on performance, and a more cross-Atlantic cast than usual. (The old-timiness of Sleeping Murder or Nemesis were never going to attract Warner Bros.)
To be honest, aside from a few melodramatic touches in the denouement, there’s nothing to be said against this film. On the other hand, aside from two gripping scenes mentioned below, there’s very little here that attempts to stand out from the crowd.
