Sharp, tightly paced low budget film is hard to categorize. There are definitely noirish tendencies but it's not a full blown film noir, there are also elements of horror contained within but neither is a horror movie. Even as a hybrid of different genres it is very involving and uses it short running time to full effect, actually so effective that it received quite a lot of critical attention in its day for a lower budget release and helped move its leading lady's career forward.
Speaking of the leading lady the film is also a study of two stars in flight. Susan Hayward whose full fledged stardom was still a few years away was still definitely on her way up, Frances Farmer, whose part is small, was most definitely on the descent. At one time considered an actress with the brightest of futures this was her second to last picture before descending into a decades long hell of mental illness and involuntary confinement.
The real standout though is Albert Dekker in a dual role of very different twin brothers. An excellent character actor who met a grisly end he rarely had the opportunity of the leading role but he takes his chance here and makes the most of it. His body language and vocal inflections makes the two characters recognizably different men and their struggles relatable. Not readily available and hard to find its definitely worth the effort to seek out.
