While the City Sleeps (1956), directed by Fritz Lang.
The lives, loves and office politics of reporters while a strangler runs wild in the city. We have a decent five minutes of chasing in the streets and subways, but the rest is soap opera.
Despite that, the strong veteran cast is good: Dana Andrews, Rhonda Fleming, George Sanders, Howard Duff, Thomas Mitchell, Vincent Price and Ida Lupino. I had the feeling that some of the cast were drunk during filming: I know Andrews had alcohol problems for a while, and here it's hard to see if his hard-drinking reporter performance is entirely an act.
The psycho-killer is son of John Barrymore, father of Drew.
