This isn't a comedy/thriller, it's a romantic comedy that all of a sudden realises it's meant to be a thriller at approximately 15 minutes to go. It's all set in a hotel in England, owned by Saturday Keith ("he's one of 7 boys, all named after the days of the week!") and its other main players are the various guests that happen to be staying there in one particular week. Reminded me a little of Separate Tables. Now, nothing is explained too well, so halfway through the film you're apt to be thinking "huh? why is so and so doing that?" well never fear because just when it gets thrilling (kidnapping, car chase and all!) near the end, everyone all of a sudden feels the need to explain their story, and almost no one is what they seem. It only runs for about an hour and 10-15 minutes, and even if it's confusing and unexplained for the most part, it still holds your attention (I guess because you're wondering what the heck is meant to be going on), and I found myself really enjoying it. The comedy is splendid, and Joyce Grenfell plays her part to a tee. The romance is sweet, and while some scenes seem a bit ridiculous, it's never tacky or silly. Overall, 9 out of 10. I would have given it a 10 if they'd made things a bit more clear earlier on, and also explained the deal with the play/show/production/thing a little better!
