A movie based on a recent book that's based on another book from 1902 - that's the backstory of the new film Four Kids and It.
E. Nesbit's original novel Five Children and It is the story of an Edwardian family that comes across an ancient magical creature called Psammead with the ability to grant wishes that last for a day.
British writer Dame Jacqueline Wilson was inspired to write Four Kids and It 110 years later, in 2012. She gave the story a contemporary spin, with children from a newly blended family coming across Psammead and wishing to time travel.
Now Four kids and It is a movie, with the magical creature voiced by Sir Michael Caine, while comedian Russell Brand plays the arch villain.

The movie Four Kids and It opens around the country on 24 September.
