Entertainment Weekly reports that Henry Thomas -- best known as one of the stars of Netflix's breakout horror hit The Haunting of Hill House -- has joined the series as Doctor Mid-Nite, a Golden Age DC Comics hero and vital member of the JSA.
Doctor Mid-Nite first appeared in 1941 as the alter-ego of a gifted surgeon named Charles McNider. While trying to remove a bullet from a man about to testify against gangster, McNider was caught in a grenade explosion which left him blind, effectively ending his medical career. One night an owl flew in his window and pulled the bandages off his eyes, and McNider realized that he was miraculously able to see in total darkness. He eventually invented a visor that allowed him to see in the light, as well as his signature "blackout bombs" which cast the world around him into darkness, and became a costumed hero and member of the JSA. He also kept the owl as a sidekick.
Thomas, also known to genre fans as Elliott from Steven Spielberg's E.T., joins a cast that already features several key JSA members, including Hourman (Lou Ferrigno Jr.), Starman (Joel McHale), and Wildcat (Brian Stapf). Since Courtney Whitmore (Stargirl's real name) spends a lot of her early heroic years surrounded by these veterans, it's no surprise to see the team coming together like this.
Stargirl arrives on DC Universe sometime next year.
