Suspenseful and entertaining but not one of the best of that era. Stellar cast Including Charlton Heston Martin balsam David Janssen Jack Klugman John Cassavetes Gena Rolland’s And Mitchell Ryan. Mostly a great suspense film because you never saw who the sniper was until the last frame. I was a teenager back then and was part of the disaster genre of that time so I rate it three stars.
