Other reviews here have quite rightly highlighted what a poor film this is. The fault lies pretty well entirely with the production and direction. It is potentially a good story - but this story had been done before and since always to better effect. The screenplay is pedestrian and makes nothing of the opportunities for tension and character development. Direction seems to be non-existent with the poor actors doing the best they can with poor material. Nothing is made of the iconic Viennese setting, the drama of the border crossing or the constant tension of the protagonist being a hunted man. If this were not bad enough the cinematography, lighting and sound are distinctly amateur.
Is there anything of value in this then? . Well Theodore Bikel shows early signs of the genuine talent that would become more apparent as his career developed. John Bentley gives a dependable performance in line with his more famous "Paul Temple" role. Of interest is Donald Grey who became better known on screen in the TV series "Saber of the Yard" where as a one-armed actor he chose to play the detective with an empty sleeve. In this he wears a prosthetic arm carefully turned away from the camera. Probably because of his disability and distinctive voice, in his later career he became known for voice overs, most notably in Gerry Anderson's Captain Scarlett.
Finally, anyone interested in film composers may detect the uncredited early work of Edwin (Ted) Astley here. This is from the beginning of Astley's career, before he developed the distinctive ITC style that provided the scores for The Saint, The Baron, Danger Man and many other great TV series of the 70's. Here, his style is complex and orchestral, borrowing ideas and actual cues from "Scotland Yard" an early 50's TV series by him.
