VIDEO : 'Mary Poppins Returns': Reactions Online

The holiday box office is shaping up to be extremely promising as early reviews for Mary Poppins Returns roll in. For the most part, the upcoming Disney sequel is garnering positive and joyful reactions with only a few complaints. The new film is also set to star Lin-Manuel Miranda, Emily Mortimer and Ben Whishaw, and will feature appearances by Dick Van Dyke, Meryl Streep, Julie Walters, Colin Firth, Pixie Davies, Joel Dawson, Nathanael Saleh, Angela Lansbury and David Warner. There's an added bit of rivalry between the films now that we know Julie Andrews, the original Mary Poppins, is making a cameo appearance in Aquaman.
