beware and my lovely be an experimental studio film from the early fifty and be direct by a man and harry horner and good know for his set design . robert ryan play a handyman who be hire by ida lupino to do some housework for her . the problem be that he be a psychopathic murderer and doesn not know it . miss lupino be an empathetic soul and try to win ryan over and to little avail . he be not the sort of man compassion could help or cure . thus we have an interesting situation of two people who basically mean well and but one of them can not do well because there be something wrong with him . he suffer periodic blackout during which he commit act of violence and which he later forget . essentially the effect ryan have on lupino be that of the hunter and his prey and or in another sense a sadist . the audience find out early on that ryan be a mad killer and but it take lupino much long . thus we must live with this knowledge a we watch poor miss lupino try everything in her power to win ryan over in order to make thing work and get the job do and get on with life . but get on with thing isn not in ryan makeup and a he be incapable of any but the most rudimentary form of normality and and as soon a there be an open his paranoia assert itself . a a study in mental illness the movie isn not too impressive . what it superlative at be show the effect of major mental illness and with dangerous psychopathology in the mix and and it effect on a normal person . in this regard the film be realistic and compassionate and though relentlessly logical in that we know lupino can not fix ryan and yet we want her to . the result be that and if one be willing and one can get extremely involve in this film emotionally if one can put aside and so to speak and it melodramatic structure . horner show u and gradually and the layout the lupino house and a forbidding gothic monstrosity that never feel like a home . we become familiar with staircase and kitchen and pantry while and we come to know which windows miss lupino can use for an escape and which one she can not .
