Stunt player A.J. Bakunas died doubling George Kennedy in a fall that killed Kennedy's character. The scene had been shot safely with the stunt man jumping from the ninth floor of the construction site/shooting location in Lexington, KY. At the time he held the record for high falls, set while doubling Burt Reynolds in Hooper (1978), but when rival Dar Robinson later beat his distance in a helicopter jump at Knott's Berry Farm, A. J. and Lee Majors returned to the star's home state to re-shoot the opening of the movie with Bakunas actually jumping from the top of the building. He fell correctly onto an airbag, but the airbag split on impact. His father was with him at the time of his death, but his mother never visited A. J. on set because she always feared he would be killed. Ironically, the completed structure, Kincaid Towers, became home to a life insurance company that eventually went bankrupt.
There was a scene filmed, but did not make into the movie that was filmed on South Broadway in between Boots Hotel and a restaurant involving a intoxicated man with a bottle of Makers Mark with a brown bag covering the bottle and he walks towards Lee Majors asking him for money while Majors is driving a white car.
A wooden "mock up" set was constructed on the roof of the nearby Patterson Office Tower on the University of Kentucky campus. Most of the top floor scenes were filmed there, as to not interfere with the actual construction in progress at Kincaid Towers (the stand-in for Hayes Plaza Tower depicted in the film)
