A fondly-remembered melodrama  thanks chiefly to Ronald Colman's fine Oscar-winning central performance  about an oft-treated theme: the nature of acting and how it can overtake one's perception of reality. In this case, we have a well-known thespian tackling Shakespeare's "Othello", so that the film's last third delves effectively into the thriller genre  with press agent Edmond O'Brien (who happens to really be besotted with Colman's co-star and ex-wife Signe Hasso) 'investigating' the actor's possible involvement in the Desdemona-like strangling of a celebrity-seeking waitress (a very slim Shelley Winters). The theatrical/New York atmosphere of the immediate post-war era is vividly captured by the husband-and-wife screen writing team of Garson Kanin and Ruth Gordon and legendary "actor's director" George Cukor (all of whom were recognized by the Academy with nominations); incidentally, the film nabbed a second Oscar for Miklos Rozsa's eclectic score. Colman, forever the suave leading man blessed besides with a velvety voice, does well enough by Shakespeare  gaining conviction the farther his character slips into obsessive jealousy, a murderous rage and, eventually, paranoia; however, he is not let down by a supporting cast which also includes director Ray Collins, reporter Millard Mitchell, detective Joe Sawyer and coroner Whit Bissell. Though the mid-section is a bit strained, the film makes up for any deficiencies with a remarkably-handled Expressionist denouement.
