2. Mademoiselle - Martyrs

If you've seen the infamous yet iconic French horror Martyrs, then you already know why it's on this list. This unexpected death is more than a simple piece of shock value; it's the key to one of the most tantalising questions in cinematic history. Sadly, it's one that you'll never know the answer to. 

To explore this death, the entire plot of Martyrs will need to be spoiled, so here's an additional warning. 

Martyrs is a gruesome film that slowly unveils a grand conspiracy led by the mysterious Mademoiselle to uncover the secrets of the afterlife. After doing some heinous things, this vile woman finally learns the truth after the protagonist, Anna, whispers it to her. How does she respond to finally learning the secrets she's spent years torturing people to learn? Well, by gathering up all of her rich compatriots and then suddenly shooting herself just before the credits roll. 

This abrupt demise leaves so many lingering questions. What did she learn? Why did she do it? Why were her last words "keep doubting"? Unfortunately, this antagonist takes those answers to the grave with her.
