Adapted from the stage thriller The Man (itself based upon a half-hour radio drama), Beware My Lovely is a taut suspenser tailor-made for the talents of Ida Lupino and Robert Ryan. Lupino plays a pretty widow who impulsively hires handyman Ryan to look after her house. She soon learns Ryan is a dangerous schizophrenic, but by the time she comes to this realization she is unable to escape her house. The tension mounts apace, leading to an unexpected but quite logical finale. Produced by Lupino's then-husband Collier Young, Beware My Lovely was released by RKO Radio. ~ Hal Erickson, Rovi
