Yes, including John Dee (David Thewlis) cheating a bit because he is a main villain in the TV series Sandman. However, he has been in DC comics for decades and some fans will know him better as Doctor Destiny. He first appears in 1961’s Justice League of America #5, where he attacks the team by disguising himself as the Green Lantern – before escaping with an anti-gravity machine. But the villain’s later appearances involve the Materioptikon, also known as the Dreamstone, using it to reshape reality as he sees fit. The unfortunate side effect of this is that Destiny becomes emaciated due to its addiction to the Dreamstone.
While John Dee has a skeletal appearance in the “Sandman” comics thanks to his years of using the Materioptikon, actor David Thewlis just delivers an intense performance to intrigue the villain’s curiosity with heartbreak, pain, pleasure and all to express in between. The live-action series has a little more nuance in creating its own world – meaning Thewlis doesn’t have an elaborate purple costume or flashback to skirmishes with the Justice League. But realistically, this also ensures the series doesn’t step on DC’s toes when it comes to iconic characters and franchises.
