Netflix's upcoming series Locke & Key has added Connor Jessup (Falling Skies, American Crime) and Emilia Jones (Utopia, Residue) to its cast.

According to Deadline, Jessup and Jones will play brother and sister, Tyler and Kinsey Locke, respectively. They will be joining Jackson Robert Scott (It, Fear the Walking Dead), who plays the pair's younger brother, Bode Locke.

Based on writer Joe Hill and IDW Publishing's popular comic book series of the same name, Locke & Key follows the three Locke siblings as they move back to their ancestral home in Massachusetts following the murder of their father. Upon arriving, they discover magical keys that give them various supernatural powers. Unfortunately for them, however, these keys are also sought after by a nefarious demon.

This past July, it was officially confirmed that the series had been greenlit for a 10-episode season at Netflix. A pilot for Locke & Key, which had already cast Scott as Bode Locke, was originally being developed by Hulu. However, the Los Angeles-based streaming service ultimately decided not to order it to series.

The project was then picked up by Netflix, who opted to keep Scott as Bode, but recast the roles of Tyler and Kinsey, which have now been given to Jessup and Jones.

Locke & Key does not currently have a release date.
