'Inner Sanctum' is, although quite interesting and thrilling, wasted opportunity as quality film-noir. The film opens with a scene on a train where elegantly dressed woman meets Dr. Valonius (Fritz Leiber) who tells her the story about woman being killed be her fiancee. We then are thrown in the story in the midst of the killing scene. Harold Dunlap (Charles Russell) accidentally kills the woman who's attacking him. He is shocked by his deed, and rids himself from the body by throwing it on the back of the departing train. Unfortunately, young kid Mike (Dale Belding) sees Harold dumping the package on the train. Harold tries to flee the small town, but all the roads are closed because of the floods. He is picked up by local newspaperman McFee (Billy House), who drops him off at the boarding house ran by his close friend Mrs. Mitchell (Nana Bryant). In there Harold meets a young woman Jean (Mary Beth Hughes), who herself with a shaded past, starts to feel immediate sympathy towards mysterious Harold. Unfortunately, in the same house lives the boy Mike with his mother, and when the stories about the dead woman found on the train, reach the town, Mike starts to but one and one together.
The film has nice eerie atmosphere, and the story inside the story is interesting with Dr. Valonius storyline drawing nice circle around the main plot and neatly tying the knots. But the film seems bit rushed, as the director haven't allowed the psychological tension between the character grow enough. Otherwise neat little film-noir that manages to keep the viewer interested enough to sit through barely over an hour running time.
