I've read quite a few Agatha Christie books and, for all its ingenuity, "And Then There Were None" is one of the silliest. It's a good, fun read but the outrageous plot completely falls apart under even the mildest scrutiny. For example, you'd think that pulling off ten [sic] murders without getting caught would be a thorny enough problem for a homicidal maniac, without the added artistic flourishes of referencing a nursery rhyme and removing/destroying symbolic figurines! The longer the story goes on, the dafter it gets, because the simple fact is you cannot shepherd intelligent people to their doom quite so easily; heaven knows, I've tried! Only kidding! Anyway, for the most part, René Clair's film wisely opts to play for laughs. The performances are a bit hammy at times, but delightfully so. The ending, which is based on Christie's own 1942 stage adaptation, will seem radically different to those familiar with the novel. As a product of Clair's tenure as an exile in the US, I much prefer "I Married a Witch", with Veronica Lake.
