I have around 80 Hammer films in my movie collection and this is the earliest one (due to its inclusion on "The Mummy" Blu Ray as a special feature). I'm embarking on a Hammer movie marathon for 2018 - viewing them in production order. This film kept me intrigued for most of it's short duration though the ending seemed rushed and lacklustre. Adequate performances from the leads - I have never seen or heard of Paul Henreid or Lizabeth Scott before but I found them both very watchable. The premise is fairly ridiculous and the plot rather lightweight but there were entertaining scenes throughout. The direction and editing was quite good for a low budget black and white film that is 66 years old. 4/10 - Fair
