10 Movies That Took Insane Steps To Prevent Spoilers

If Endgame was the final boss of spoiler secrecy (at least so far), Alfred Hitchcock's Psycho was the godfather that started it all. Nicknamed 'Master of Suspense', his desire to keep his audiences guessing reached its peak with the release of (arguably) his best-known film.

He first started by creating a policy where nobody is allowed into the theater once the feature began, and then did all he could to promote it. Anyone waiting in line to watch Psycho in cinemas was treated by a voice recording from Hitchcock urging them to abide by his rule, and then even once inside the theatre, signs and cutouts were displayed to encourage its use. The policy wouldn't even have been a surprise to most, as numerous ad campaigns were also run, including one in which Hitchcock compares Psycho to a three-course meal and insists that the policy applies to everyone - even "the President of the United States or the Queen of England (God bless her)".

Even advance screenings for critics were off the table for this one, fearing word of mouth alone would spoil it for some. Though one might describe these actions as 'psychotic', they actually proved tremendously successful for everyone involved.
