The film opening of 'Dirty Harry' is effective through its use of clever Camera Shots, especially the Point Of View (P.O.V) shot which shows the killers perspective through the sight in his sniper rifle, as he stalks his target. The film was also influential for its Mise-En-Scene, and how the protagonist Dirty Harry, and his rival were portrayed, through the use of clothing, props, etc.
'The Usual Suspects' opening is also effective as it combines use of slow and smart Editing with an eerie, thriller styled Soundtrack. Slow cuts are used in order to make the audience watch more closely than normal, as the opening is purposing made to be confusing. This is also associated with the music, which is used to add tension and build suspense.
