As Seen In: Mirrors (2008)
This one's for vain people everywhere. In the world of Mirrors, stopping to check out your mug is deadly, as your evil reflection has an entirely different agenda: kill its physical counterpart.
In the otherwise disappointing 2008 horror flick Mirrors, Angela (Amy Smart) is checking herself out in a bathroom mirror, pre-bath, when her reflection grabs both rows of teeth by the hands and pulls in opposite directions, stretching her mouth region way beyond its natural limits. Lockjaw on a hundred thousand.
