When the film Mary Poppins was released in 1964, it was a heartwarming tale of a magical nanny who gets the unruly Banks children to behave by being firm yet gentle with them. By the time she leaves the children, their father has become a better dad and everything in the world is right. The movie was loosely based on a series of books, and it has been a beloved tale for children for some time, regardless of when they were born. Yet if you look at the film differently, you might find it to be more sinister than heartwarming. Is Mary really someone you want in your house? Here’s what the trailer may have looked like if Mary Poppins was a horror flick.
