Wait Until Dark
It says something about how good a movie is when you found it by reading a spoiler on a list called The Top 50 Movie Endings of all Time, and you’re still on the edge of your seat.
Audrey Hepburn was nominated for an Academy Award and a Golden Globe for her portrayal here of Susy Hendrix, a blind woman whose husband accidentally comes into possession of a doll filled with heroin. As three criminals try to find the doll in Suzy’s apartment, the level of tension rises to that of Rear Window and more recently Red Eye. At times it’s a little cheesy, as movies made in the 60s can be, but it’s worth it by the time you get to the ending.
