The Tesla CEO has spoken at length about his love for sci-fi classics like "Star Wars" and "Bladerunner," and even had a cameo this year as an alternate version of himself in the sci-fi parody series "Rick and Morty."

But in 2019 the film that most captured Musk's imagination was the critically acclaimed "Parasite," as Musk revealed on Twitter on Christmas Eve.

"Parasite" is a South Korean satirical thriller written and directed by Bong Joon-Ho. The plot revolves about members of a poor family inserting themselves into the life of a rich one. Slate compared the film to Jordan Peele's "Us."

The film won the Palme D'Or at Cannes, and is tipped for an Oscar.Another Twitter user asked Musk what his favorite Netflix series is, to which he replied "Black Mirror," the tech-inspired dystopian anthology series by Charlie Brooker.
