Vic Morrow's last completed film was 1990: The Bronx Warriors (1982). In an eerily prescient scene that seemed to foreshadow his tragic death in this film, Morrow's superior says to him, "If you don't get the girl by 11 o'clock tomorrow, I'll have your head!" Morrow's character replied, "We'll fly her in, in a helicopter."

On October 23, 1982, O'Neill suffered a gunshot wound in her home on McClain Street in Bedford, New York. Police officers who interviewed O'Neill determined that she had accidentally shot herself in the abdomen with a .38 caliber revolver at her 30-acre, 25-room French-style estate while trying to determine if the weapon was loaded. Her fifth husband at the time, John Lederer, was not in the house when the handgun was discharged, but two other people were in the house. Detective Sgt. Thomas Rothwell was quoted as having said that O'Neill "didn't know much about guns."
On October 12, 1984, O'Neill's co-star in the Cover Up television series, Jon-Erik Hexum, mortally wounded himself on the show's set, unaware that a gun loaded with a blank cartridge could still cause extreme damage from the effect of expanding powder gasses. He died six days later. Source.
