In an earlier version Andre' Deveraux and Granville, the Russian spy, agree to have an old fashioned duel with pistols in an empty stadium. But before the duel begins, Granville is shot in the back by a Russian sniper to silence him. This finale was deleted and a new one shot, because early audiences didn't like it. These scenes were considered lost for many years, until director
Richard Franklin discovered that they had been lying for years in a can in Hitchcock's garage and were given by his daughter to the Academy of Motion Pictures Arts and Sciences after her father's death.
