I remember this film used to be shone on PBS, now and again, and I always looked forward to watching it.(this was before VCRs, so I caught it when it braodcasted) It was one of the better low key spy films to come out during the James Bond phenomena of the mid 60's, a light comedic film that turned into a good suspense thriller by the end. I hope somebody acquires a good print and puts it out on DVD.
