According to Variety, the character will be a series regular in the fall drama. Unlike her comic book counterpart who served as a fashion reporter for the Daily Planet, this Cat Grant will be "a self-made media magnate and founder of CatCo."
Best known for her role in the '90s single female lawyer classic "Ally McBeal," Flockhart previously worked with "Supergirl" executive producer and developer Greg Berlanti on the ABC show "Brothers & Sisters." She joins lead actress Melissa Benoist as Kara Zor-El, Mehcad Brooks as Jimmy Olsen and Laura Benanti as Supergirl's mother Alura.
Introduced in the 1990s Superman comics by creators Marv Wolfman and Jerry Ordway, Cat Grant has become a major fixture of the Super world. She's appeared on screen live twice before - played by Tracy Scoggins in "Lois & Clark: The New Adventures of Superman" and in two different iterations on "Smallville."
While housed on a separate network from the Berlanti-produced "Arrow" and "The Flash," "Supergirl" may be set in the same universe as those shows (appearing on CBS' sister network The CW). It is expected to debut this fall.
