EDIT: Here are the rules as clarified and revised, with excellent suggestions provided by others. Thanks.
Step 1: Pick a spoiler that hasn't already been answered and name the film it spoils.
Step 2: Spoil a different film using three or fewer words.
Your answer does not have to be right or confirmed to be right before you can proceed to Step 2. Please feel free to spoil another film after answering a previous spoiler.
(Preferably one that hasn't been used in this thread before and preferably a "classic" using whatever standard for "classic" you wish, but do it in good faith please).
I'll start. Name the film and then add your own three-word-or-less spoiler for another classic film for the next poster.
