Mary Poppins - one of my favorite films as a kid. We had it on VHS and I drove my mother nuts asking to watch it multiple times a week. I also remember jumping out of the tree in the backyard with an umbrella to see if I could fly... luckily the limb I jumped from wasn't that high :-)
Disney just released the trailer to Mary Poppins Returns with Emily Blunt as the star. She shows back up to the home of the grown children from the first movie to help them find their way. A few OGs from the original film make appearances too in the film including Dick Van Dyke!!!
