Claysaba Excellent, Without a doubt!!

Livestonth I am only giving this movie a 1 for the great cast, though I can't imagine what any of them were thinking. This movie was horrible

Fairaher The film makes a home in your brain and the only cure is to see it again.

Yvonne Jodi Unshakable, witty and deeply felt, the film will be paying emotional dividends for a long, long time.

ags123 A slow moving thriller with no thrills, suspense or logic to it. Anthony Perkins turns in an unconvincing performance as a brain surgeon and criminal mastermind. Charles Bronson, playing an amnesia victim, spends the whole time looking lost and confused; Maybe he thought he was part of the audience. Jill Ireland looks good but shows no real talent for acting. The lack of a tense background score (Instead, a movement from Dvorak's "New World Symphony" plays on a record player) makes the proceedings seem even more dry and lifeless. The tedium goes on far too long, with scant reward for those viewers who make it to the end. Cannot recommend this film.

MARIO GAUCI I'd always been interested in watching this one (which occasionally turns up on late-night Italian TV) due to its star combo; now that I've caught up with it, I found it to be an intriguing if deliberately-paced psychological puzzler – where, as was the case with the later THE LITTLE GIRL WHO LIVES DOWN THE LANE (1976), director Gessner demonstrates himself an unsung master of the offbeat and provocative thriller. Leads Charles Bronson and Anthony Perkins work very well off each other; while the latter has played this type of role before (it's what he does best, yet given enough subtle shadings to retain an element of surprise), the former credibly stretches his range with his amnesiac role (duped into committing murder by Perkins' scheming cuckolded doctor).Most reviews I've read seem unable to swallow the central premise – that Perkins would devise the perfect crime by 'brainwashing' Bronson into believing himself to be a totally different person – but I feel that it works most of the time mainly due to the excellent leads (nearly falling apart at the climax but picks up again nicely with the ending, as Bronson's memory is suddenly jolted back through ironically similar circumstances and his real-life spouse Jill Ireland confronts on-screen husband Perkins with his failure as both doctor and man). The film, then, concludes on a marvelous note – a series of close-ups, alternating between Ireland and Perkins, that follow the rhythm of a beating heart (though the effect is somewhat dissipated by going on too long).My viewing of SOMEONE BEHIND THE DOOR came via a public-domain print on a budget DVD I rented (which slapped this Bronson title together with two other lesser vehicles – GUNS OF DIABLO [1964] and COLD SWEAT [1970], both also watched recently). I'd like to own the Gessner film someday; at least, I know it's available in widescreen on a bare-bones disc from Lionsgate – though I wonder how long it will stay in print...

gridoon Back in the good old days, before the success of "Death Wish" forced him into playing the same role of the angry vigilante over and over again, Charles Bronson was a fine, versatile actor; in this 1971 film, he actually plays the victim of a larger scheme (though he does some victimizing of his own, too), and he's the best - if not the only - reason to see this otherwise static, plodding thriller. Anthony Perkins disappoints as the slightly deranged brain surgeon. The version I saw was in French, though the actors clearly spoke English on the set; this only added to the strangeness of the experience. Oh, and good luck to anyone trying to figure out what the title has to do with anything else. (**)

Zorin-2 "Someone Behind the Door" is not bad but not great either. It still is better than most of Bronson's other films but this film is not recognized because it is so rare. I would never have found out about it if it weren't for accidently running across it in a video store. Charles Bronson plays an amnesia victim who is taken in by doctor Anthony Perkins. But Perkins has a plan to kill his wife so he convinces Bronson to murder her. "Someone Behind the Door" might disappoint some of Bronson's fans because it does not have the violence that is other films have.
