Hint... it's not one of the "kids"

As the official synopsis says...

Four Kids and It is a charming and whimsical story featuring a star-studded cast including Paula Patton (2 Guns, Mission Impossible: Ghost Protocol) and Matthew Goode (TV’s “Downton Abbey” and “The Crown”), with Russell Brand (TV’s “Ballers,” Forgetting Sarah Marshall) and the voice of Academy Award® winner Michael Caine (1999, Best Supporting Actor, The Cider House Rules; The Dark Knight franchise, The Prestige). Based on iconic children’s author Jaqueline Wilson’s Four Children and It, the story is a modern twist based on E. Nesbit’s 1902 classic Five Children and It, and also stars Teddie Malleson-Allen, Ashley Aufderheide, Billy Jenkins, and Ellie-Mae Siame. The film adaptation is directed by Andy De Emmony (TV’s “The Nest” and “Spitting Image”) and written by Simon Lewis.

On a seaside holiday, four kids from a blended family visit the beach, where they discover a floppy-eared creature that grants their wishes. But there’s a catch: the kids’ adventures in rock-climbing, pop stardom, and flying end promptly at sunset — leaving them in danger each time. Can they learn to control the magic before something dreadful happens?

Four Kids and It will be available on Blu-ray, DVD, and digital platforms on June 30, 2020.
