'On Dangerous Ground' is a very original and striking movie, one of the most interesting to come out of 1950s Hollywood. The movie is in two halves. The first is urban and sees Robert Ryan play Jim Wilson a brutal but seemingly moral cop who appears to be on the brink of a complete breakdown. His character could well be the toughest cop ever seen on screen until the early 1970s heyday of Dirty Harry and Popeye Doyle,etc. The second half is rural, with Wilson being sent out of the city to investigate the murder of a young girl (shades almost of Stellan Skarsgard in 1997's 'Insomnia'). There he encounters a local blind woman (Ida Lupino), the sister of his number one suspect. The first half is as I said, extremely tough, the second half is ALMOST a mystery (yet it's obvious who the murderer is), and ALMOST a romance (but handled in a very subtle and "unHollywood" way). It's an odd combination but really works because the script lacks cliches, Nicholas "Rebel Without A Cause" Ray's direction is very fresh and inventive, and the acting is first rate. Lupino makes the most of her supporting role, as does Ward Bond ('The Searchers') as the father of the murdered girl, and Sumner Williams as Lupino's disturbed younger brother, but Robert Ryan steals the movie. I'm beginning to regard Ryan as one of the most underrated screen actors of all time. Just watch him in this, the boxing classic 'The Set-Up', 'Crossfire', 'Bad Day At Black Rock', and of course, 'The Wild Bunch' and see what I mean. 'On Dangerous Ground' deserves a much larger audience. Highly recommended.
