Threat, The (1949) - (Movie Clip) Open, Kluger's Out
Straight to business, no attempt to disguise the locale (L-A) or the state prison (Folsom), but only Robert Shayne as cop Murphy is properly introduced, though the danger (in the person of un-seen Charles McGraw) is made clear, in The Threat, 1949, directed by Felix Feist, with Michael OShea and Virginia Grey.
