This is among the director's most popular works, being the one that overtly played him up as a potential rival to Alfred Hitchcock (complete with Castle's cheeky introduction a' la Hitch's own TV appearances); at the same time, its deliberate nods to PSYCHO (1960) did not really endear it to critics but, of course, audiences at the time lapped it up
which only goes to prove just how much of a milestone the Hitchcock classic was when it first emerged and has remained so over the years through countless imitations!
Anyway, taken on its own merits, the film is certainly an above-average chiller for Castle – yet one is left wondering whether he was audacious or foolhardy in his approach towards the all-important plot twist; Hitchcock was certainly wiser in keeping "Mother" in the background, whereas Castle throws the secondary personality of the titular figure in our faces almost from the get-go! Indeed, the prologue should have been omitted entirely – as it really gave the game away to discerning viewers. The transvestism element, then, elicits unwarranted comparisons throughout with Ed Wood's notorious GLEN OR GLENDA? (1953) – but the PSYCHO borrowings, at least, are fairly well integrated into the narrative: a stint by the blonde leading lady at a run-down motel, a near-brush with the Law, a nosy investigator, an invalid also staying at the house, the put-upon young couple, etc. Having said that, the aforementioned prologue, the sadistic mistreatment of the latter character and the underlying "greed is the root of all evil" theme clearly anticipate the next phase in Horror film-making: the "Grand Guignol" chillers spearheaded by Robert Aldrich's WHAT EVER HAPPENED TO BABY JANE? (1962)
Still, while it also has an early and would-be shocking (because apparently unprovoked) murder – that could have pointed out to yet another childhood sexual trauma in other scenarios – one cannot sensibly compare the impact of the bloody yet extremely clumsy stabbing of James Westerfield with the legendary shower sequence from PSYCHO involving Janet Leigh! Incidentally, even if we do get to hear the two personalities speak in the same sequence (as Anthony Perkins did in the earlier film), their never actually appearing together – to say nothing of the man's distinctly effeminate appearance – should have alerted audiences as to the nature of the ruse (not that her eventual uncovering – preceded by the gimmicky 45-second "Fright Break" – is totally ineffective, unlike her ultimate come-uppance
which comes off as rushed)! Casting-wise, it is obviously Jean Arless (actually Joan Marshall, who adopted the pseudonym so as not to be typecast, but her subsequent roles were negligible at best!) who makes the biggest impression, whereas Eugenie Leontovich's stroke victim – with her incessant banging to attract attention – gets on one's nerves very quickly!
