Variety — After the success of “Chernobyl,” Sky and HBO are teaming again, this time on “The Third Day.” Jude Law will star in the six-parter, which will be the first original from Sky Studios, the Comcast-owned pay-TV giant’s new production unit that was announced Wednesday. Sky will produce alongside Plan B, immersive theater outfit Punchdrunk International, and series writer and co-creator Dennis Kelly (“Utopia”).

Law stars as Sam, who after being drawn to a mysterious Island off the British coast, is thrown into the unusual world of its secretive inhabitants. Isolated from the mainland, the rituals of the island begin to overwhelm him, and he is confronted by a trauma from his past. As the line between reality and fantasy blurs, Sam finds himself immersed in a quest that puts him at odds with the islanders.

Marc Munden (“National Treasure”) will direct and Adrian Sturges (“Chimerica”) produce.

“‘The Third Day’ is the result of the intoxicating combined imaginations of Dennis Kelly and Punchdrunk International’s Felix Barrett,” said Cameron Roach, Sky U.K. and Ireland’s director of drama and Sky Studios. “To see them brought to life under the direction of Marc Munden and with Jude Law at the helm of what promises to be a world-class cast is an incredibly exciting prospect.”
