WATCH: We chat with the cast and creators of Mary Poppins Returns on the red carpet

Mary Poppins Returns is set to hit theaters on December 19 and we hit the red carpet in Hollywood to chat with some of the cast and crew, including Ben Whishaw, Emily Mortimer and more!

Check out our coverage below and learn about what it was like for Mortimer to meet the original Jane Banks on set, working with Dick Van Dyke and how they gender-swapped the character of Topsy so Meryl Streep could be involved with the film.
