Continuity mistake: Shortly before Sol's death, Thorn rushes into the suicide center and talks to him from the control room above. When Sol pleads Thorn to listen, there's interference on the intercom. Now watch the control panel: The earphone cable on the left side dangles back and forth each time the "speaking permitted" sign flashes on and off, blatantly revealing the cheap trick they used to make the display flashing - they simply toggled the "on" and "off" frames.

Martha Phillips: I should've offered you something, Mr. Thorn.
Det. Thorn: If I'd had the time, I would've asked for it.
Trivia: This was Edward G. Robinson's last film.
