"Call Northside 777" is a well made crime drama shot in semi-documentary style. It benefits from a solid script, and tight direction (by Henry Hathaway). It also features a naturalistic James Stewart as a sharp investigative reporter; much of the success of the film is due to his thoroughly convincing performance. A fine support cast includes Richard Conte, Lee J. Cobb and Helen Walker. What ages the film a bit is the now somewhat dated technology featured (a lengthy episode in which the lie detector is treated in detail, along with certain photographic reproduction and transference techniques). Yet, one can view these aspects as historically accurate representations, and enjoy the total production, which is on a commendably high level.
