Supergirl Casts Katie McGrath As Lena Luthor

A month or so back came the news that Lex Luthor’s less nefarious sibling would be making an entrance into Supergirl. The question was, of course, when would the actress playing her be unveiled? Well, now we know who’s tackling the part, as TV Line reports that Merlin’s Katie McGrath has signed up for the recurring role.

Here’s how the site describes her introduction:

“Beautiful, powerful, and enigmatic, Lena arrives in National City on the heels of brother Lex’s incarceration hoping for a fresh start. Lena has taken over as CEO of her family’s billion-dollar-tech company, Luthor Corp, which has been tarnished by Lex’s evil infamy. Her goal? To re-brand the empire as a force for good. Lena wants to be seen as her own person, separate from her brother. Kara is drawn into Lena’s sphere and must determine if she is friend or foe.”

McGrath joins a starry supporting cast for the upcoming season which includes Taylor Hoechlin as Superman, Lynda Carter as POTUS, Ian Gomez as Snapper Carr, and Floriana Lima as Maggie Sawyer. It’ll certainly be interesting to find out how Lena becomes embroiled in the goings-on in Kara’s life. More intriguing, however, is the parallel between the Lex of this small-screen world and the Lex of Batman v Superman: Dawn of Justice. Maybe it’s just a coincidence? Time will tell.

Supergirl returns for its second season on Monday, October 10 on The CW.
