I am big of fan of straight & classic mystery films. Give me an old house, some rocky chairs, snow (or thunderstorme), a dubious cast of mediocre to no talent and some murders and I am as a happy as poirot with a menthe tea ! This one is no exception. Yes, some moments are campy and some of the 'actors' are so awful, it made me laugh out loud, but oh the suspense and oh the evil eyes of the villain, I just adore it. Of course, I am a genre enthusiast, many out there might not share my opinion on this hidden gem. The story is pretty solid, it is a Christie after all and I found all the film versions to be good ones, hard to mess this one up. George Pollock is what I call a straight hand when it comes to directing, no flash, no dazzle, no strokes of genius but getting the job done, keep the picture in the frame and off you go. The cast is good and all the people involved play to their strength, Hugh O Brian is a handsome dervish, Fabian a moron and Wilfrid Hyde-White is a scheming and flamboyant judge ... all in good order. There are some surprises here, Mario Adorf plays a prominent role ( a great german actor) and I did very much enjoy Dennis Price's performances too. Like I said, Fabian, Lavi and Eaton were awful, but a good laugh. The story is good, albeit a tad unbelievable (not sure if the novel is) but then again, it is a work of ficition, but some of the scenes and deaths in the film border on the impossible and sometimes the film feels more like a ghost story than a murder conspiracy and the big reveal and explaination in the end does a great job of simply ignoring all the logical error and nobody explains some of the things you keep on wondering the whole film about (How did the murderer manage to pull that off? - Well, keep guessing, no one is ever going to tell you). Still, for fans of the genre, this is a must-see. Camp and gorgeous whodunnit !
