@didyoucatchthis: The Tragic On-Set Accident That Changed Hollywood In 1984, rising actor Jon-Erik Hexum was filming Cover Up when a devastating accident occurred. During a break, he playfully handled a prop gun loaded with blanks, unaware of the danger. When he pulled the trigger at close range, the force caused a fatal head injury. He was just 26 years old. The tragedy remains a sobering reminder that even blanks can be deadly, forever changing how safety on set is viewed.
