Amid the casting shakeup, Michael Cudlitz, who portrays super villain Lex Luthor on the series, will be promoted to a series regular. The Walking Dead alum joined the series in season 3.

"This whole experience so far has been amazing," Cudlitz told Entertainment Weekly in March. "From the collaboration with our showrunners Todd [Helbing] and Brent [Fletcher] to the incredibly warm welcome I received from Tyler [Hoechlin] and Elizabeth [Tulloch] and the entire cast and crew.”

He added: “I cannot wait to share with the fans how much fun we've been having. Personally, I've always felt Lex was just misunderstood."

Tyler Hoechlin, who plays Superman/Clark Kent, and Elizabeth "Bitsie" Tulloch, who portrays Lois Lane, as well as Alex Garfin and Michael Bishop are set to return as series regulars.

Warner Bros. Television — which produces Superman & Lois — declined to comment.

Deadline, which was first to report the news, noted the cast shakeup comes as both Superman & Lois and All American: Homecoming were renewed with significant budget cuts, which could include the reduction of the number of series regulars.

The budget of Superman & Lois is higher than other CW dramas due to the show’s special effects, according to the outlet. For the upcoming 10-episode season, the series is expected to focus on family drama in addition to its superhero plot lines.
