 Due to the film's explicit violence and uncomfortable detail of a homicidal sniper acting alone and without apparent motivation, NBC negotiated with Universal Studios to film additional scenes for its television premiere in 1978.The new scenes would detail an art theft, with the sniper serving as a decoy so robbers could escape without detection.The additional scenes, totaling 40 minutes in length, were added for the film's TV showing while 45 minutes of the original version were removed.
