Walk the Dark Street [DVD] [1956]

In this off-beat action drama, a slightly psychotic big-game hunter is obsessed with getting revenge upon the Army officer whom he believes caused his brother to suffer a fatal heart attack while he was a soldier. The hunter challenges the offending officer to a strange duel involving specially designed camera guns. With these, they are to roam the LA streets and shoot pictures of each other. Of course the hunter plans on having a real gun with which to shoot the officer. Unfortunately, he accidentally gives the real gun to the other guy. The hunter becomes so anxious that he too drops dead of a heart attack.~Sandra Brennan
