Supergirl series regular Calista Flockhart will be reducing her role in the show's second season, appearing as a "regular guest star" rather than a core cast member as in Supergirl season one. The change is reportedly due to the show's move from CBS's studios in Los Angeles to Vancouver, where CW films most of its superhero shows.
“Supergirl wouldn’t be Supergirl without the amazing Calista Flockhart as Cat Grant,” producer Andrew Kreisberg told Variety. “We are so excited Calista has agreed to continue on the show when she can. We and the audience love to see her on screen."
Supergirl season two is currently filming for an October 10 premiere.
