Great Los Angeles locations...

Only three of the reviews make any reference to the film's Los Angeles locations. From what I could tell, the majority of the film was shot in actual locations rather than studio sets. There's a great scene that takes place in Angel's Flight on Bunker Hill, which you all may remember from CRISS CROSS (1949). And there's a killer-stalking-target scene in a large fight arena, which another poster here identifies possibly as the Olympic arena in L.A. Plus lots of movement around other parts of L.A. That was the most interesting aspect of it to me. The story itself was kind of routine and relied on a Kefauver-type crime commission to give it some kind of topical feel. William Holden and Edmond O'Brien would be reunited 17 years later in THE WILD BUNCH.
