The episode’s director Hisko Hulsing said: “We endeavoured to make the animated version of A Dream Of A Thousand Cats as mesmerising and hypnotic as we could by utilising the magic of real oil paintings on canvas.

“We combined the paintings with classically drawn 2D animation, based on realistic 3D animation of telepathic cats in order to create a trippy world that feels both grounded and dreamy at the same time.”

There will also be a live-action story of Calliope from The Sandman universe, directed by Louise Hooper.

The TV series stars Gwendoline Christie playing Lucifer Morningstar, the ruler of Hell, as well as Kirby Howell-Baptiste, Lourdes Faberes and Joely Richardson.
