One of the earlier reviewers suggested that the film takes "the easy way out." I partially agree, but think that the real reason for the disappointing finale was the censors. They, in their moral righteousness, did their very best to ruin any number of UK and American films. In this case, the ending makes little sense. Otherwise, a very satisfying early addition to the film noir genre. The photography and pacing are perfect and carry the bleak mood. A minor quibble is that the notion of the lovers breaking off wasn't totally credible, but then, perhaps it was a different moral universe in the 1940s. Mason, as always, is excellent to the point that the viewer cannot take his eyes off of him (not that one would want to). Pamela is a hateful character, as from all reports, she was in real life.

A very fine neurosurgeon, impeccably portrayed by James Mason, who teaches criminology as a sideline, recounts a certain case study to a class during a lecture. The case deals with a man he deems to be sane, but who commits murder to avenge a murder. Mason, who has honed his great gift to heal, as a way of replacing the human connection his personal life lacks, has become detached and somewhat obsessive in his perspectives, as a result. Although he doesn't reveal it, to the undergraduates, we discover through the course of his story that he is the protagonist in the example he's presenting. He renders the murder as having been smoothly and successfully carried out, however we learn immediately thereafter that it actually has not yet been accomplished.Mason's skillfully controlled persona, as the neurosurgeon, is letter perfect and one gets the feeling that his assumptions regarding the way in which a guilt ridden former lady love died are most probably true. Although an inquest rules it as an accidental fall, gossipy detractors place the blame on the woman's, self-centered, opportunistic sister-in-law, who has much to gain financially by the woman's death. Mason's doctor character feels compelled, out of vanity, to justify his revenge to the unwitting students and then sets out to put the final segment of the plot into action.Murphy's law and irony prevail causing the retaliation to not come off nearly as seamlessly as planned. Moreover, while looking for a place to dispose of his murder victim's body Mason meets up with another more sardonic doctor, whom he's forced to give a ride to and is subsequently obliged to assist. Mason operates on and saves a young patient's life, only to be castigated and labeled, as mad, by the other doctor for his motives. The other doctor, who at one point is asked to fetch a medical supply from Mason's car, discovers the camouflaged body of his victim in the back seat but, without turning Mason in, rather asserts a moral dilemma, which figuratively then literally pushes Mason over the edge.The title of the film comes into play in the form of an analogy the other doctor makes to a glass precariously perched to fall, crack and break, comparing it to Mason's unsound mind. Mason gets the point and abruptly does a swan dive over an abyss, into the sea. We are left to ponder whether it was a consequence of being faced with his monumental conceit, or hypocritical notion of altruism, that ultimately causes his undoing.The noir aspects of its film techniques aside, this is a brilliant character study and Mason's superb achievement, alone, in creating a complex, sympathetic murderer makes the movie well worth viewing.

James Mason in one of his last British films before accepting that contract with MGM and leaving for America plays a doctor who may have become too detached from life. A prominent brain surgeon he accepts the case of young Ann Stephens whose eyesight he saves with a delicate operation. In the process he falls in love with Ann's mother Rosamund John.Both Mason and John are separated from their respective spouses and we never meet either of them in The Upturned Glass. But their relationship contains a mixture of guilt for both of them. Shortly after they end things, Mason hears that John falls to her death in her own home.Mason had already met Pamela Kellino and formed a bad opinion of her almost immediately. She's Rosamund's sister-in-law and Stephen's aunt and she's a selfish materialistic woman, a regular Cruela DeVille in real life. She's easy too hate and Mason courts her to get close.The film is told about 2/3 of the way in flashback as Mason lectures to a university class on the atypical murderer, the sane and logical one which he naturally takes himself to be. The rest of the film is a revealing portrayal of how Mason should be seen.The Upturned Glass is a nice bit of melodramatic noir with Mason really carrying this film. His perfect performance makes The Upturned Glass seem far better than it really is.

In this suspenseful movie, we meet James Mason as he lectures about crime to a group of students. He is an eminent neurologist. In flashback, we learn of the girl whose eyesight he's saved. In the course of doing this, he fell in hove with her mother.It's a murder-mystery; so that's as much plot as I'll give. Pamela Mason is appropriately unappealing as the woman's nosy sister-in-law. Mason, one of my favorite actors, is very good.As a suspense movie -- a noir, of sorts -- it is excellent. It positions itself as more, unfortunately. Initially, it's intriguing to realize that the central figure in the case history Mason's reciting is himself. But there are red herrings. More distracting, there is philosophizing -- not to mention a most unsatisfactory final scene.
