DOLPHINS AS SWEET AS A SPOONFUL OF SUGAR

AS IN the first film, Mary and the Banks children Georgie (Joel Dawson), Anabel (Pixie Davies) and John (Nathanael Saleh) — embark on Technicolor-style adventures.

At one point, a dolphin beckons the children into the bath tub — and leads them to an underwater fantasia. The mix of special effects and live action meant that, although the real-time filming only took four months to complete, Mary Poppins Returns spent more than a year in post-production.
