We certainly wouldn't fair well after getting shot and falling off a balcony but Mike did fine!
But the mask is the main reason this villain turns our blood icy. What is it about masks that makes a simple murderer into someone out of a nightmare?

There's plenty of other reasons that Mike Myers is a super scary man, of course.
