I’ve never seen a really good adaptation of the novel, and all productions including the stage play that Agatha Christie wrote, have a major change from the book. (I shall say no more...) The book is very taut and meticulous, almost claustrophobic, and the movie versions tend to try to open things up a bit, or get a bit hammy. But I’ve set the DVR, and I’ll give it a watch as long as it holds my interest. But I live in hope.
Indeed, that said it turns out that And Then There Were None is adapted by a writer, Sarah Phelps, who did several episodes of a BBC miniseries that a British friend I know from tech conventions told me about called Dickensian. That’s a murder mystery set in 19th century London where many of the characters are from Dickens novels, and apparently was very popular. (She told me about it because she knew that that was the conceit of my A Christmas Carol 2 novella, blending in a couple dozen Dickens characters.) Happily, I was able to track down the episodes of Dickensian and much look forward to seeing it. But I digress...
I hold out a bit more hope for And Then There Were None because of that. Also, this is a BBC production, not made for Lifetime, which is another big point in its favor. I don't read reviews, but did see a bunch of headlines, and it appears to have gotten quite a positive response.
I don't know the full cast, but it includes Sam Neill, Miranda Richardson and the wonderful Charles Dance. Here's the trailer.
