Panico nello stadio

Actors who appeared in the film's television version who didn't appear in the cinema movie included Rossano Brazzi, Joanna Pettet, Paul Shenar, James Olson, and William Prince. Warren Miller reprised his role as "The Sniper" and Charlton Heston shot three short new scenes for the television version. Heston's hair is of a noticeably different color in these new scenes.

When Pratt, the SWAT team member, is climbing up to the stadium lights platform, he is first shown in a long shot climbing up the fixed rung ladder attached to the platform's support pole. A close-up then shows Pratt climbing up the steel extension ladder that he used a moment before to ascend to the support pole. A wide shot then shows him ascending the fixed rung ladder on the support pole again.

Originally with a straightforward plot about a homicidal sniper acting alone and a SWAT team hunting him down, the network-TV version adds 30 minutes of side story, making the sniper a hired hand for a band of robbers, acting as a cover-up for an art heist. This version was conceived during negotiations between Universal Pictures and NBC in 1978, because NBC refused to air a film centered around a homicidal sniper. This version is sometimes aired on broadcast TV in the USA. In this version, the copyright and legal information titles are left out!
