My favorite is the one that recuts The Shining as a romcom.

For me, I'd have to recommend West Side Story as a zombie flick.

The Mary Poppins one is great, but sorry, I can't watch the other one because I'm just too damn scared of The Shining.

Can't watch either video properly (this monitor doesn't have a speaker or headphones) but just thought I'd say that when I first saw MP as an adult, all I could think was "too loud and annoying." (I was born some time after the movie was made, and VCRs were a long way off.) Good thing I'd read all the books already. For those who don't know, she's actually a no-nonsense tyrant who never gives hugs. What makes her shocking today is that she's "perennially unfair" and the children are expected to accept that, but what her radical in the 1930s was the idea that it was OK for child readers to ACKNOWLEDGE, even if only privately, that grown-ups could ever be unfair!

One sharp reviewer at Amazon pointed out that even the first book is not really about her, but about the children! Example:

“Are you quite sure he will be at home?” said Jane, as they got off the bus, she and Michael and Mary Poppins.
"Would my Uncle ask me to bring you to tea if he intended to go out, I'd like to know?" said Mary Poppins, who was evidently very offended by the question. She was wearing her blue coat with the silver buttons and the blue hat to match, and on the days when she wore these it was the easiest thing in the world to offend her.

(Does THAT passage reveal quite a bit about the children's attitude, or what?)

And, the reviewer said:

"Their nanny is a woman their parents would
consider rather ordinary, in fact quite common, a cockney. Her extraordinary stature in the children's eyes is due both to their seeing what
their parents miss and to their considerable lack of understanding of what is going on. The Star Child (Maia), for example, is really a desperately poor girl who cheerfully wears rags."
