The role has not yet been filled; casting will begin soon.
“We’re beyond excited to introduce iconic villain, Lex Luthor, to Supergirl and to weave him into our story this season,” Executive Producers Jessica Queller and Robert Rovner said in a statement released by The CW. “We’ve talked about having Lex on the show since it’s inception and we’re excited to have him finally arrive. We can’t wait for him to shake things up in National City and watch him go toe to toe with not only Supergirl, but his sister Lena Luthor.”
The CW notes that Lex Luthor will not be part of the 3-show crossover that airs in December.
Supergirl airs Sundays at 8PM ET/PT on The CW.
