Netflix's adaptation of the author's sprawling graphic novel series gets a behind-the-scenes look.

'The Sandman' BTS tour is presented by author and executive producer of the DC Comics and Netflix production, Neil Gaiman.

Gaiman's original comic book was first published in 1989 and blends horror and fantasy together in a world called "The Dreaming". Ruled by Morpheus, the Lord of Dreams, it's a place where we go once we fall asleep. After being trapped for decades, Morpheus goes on a dark quest to find the powers he has lost.

Earlier this year, the series announced its full cast lineup which will feature in the adaptation, and there are a number of big names attached to the ensemble. As well as two 'Game of Thrones' alums reuniting, Gwendoline Christie and Charles Dance, Stephen Fry, David Thewlis, and Irish actor from 'Smother' Niamh Walsh will also star.

In 'The Sandman' BTS video below, Gwendoline Christie talks about having to be involved in the project. In the series, she will play the role of Lucifer. Tom Sturridge also features, who will play the lead role as Morpheus, Dream of the Endless.

The sneak peek was released as part of Netflix's #GeekedWeek, which is celebrating all of the fictional and fantasy Netflix Original series and movies available on the streaming platform.

Here's Neil Gaiman giving us a behind-the-scenes look at his upcoming series, which features some of the vast sets and props which will play important roles in the upcoming fantasy.

'The Sandman' has a 2022 release date attached.
