Chasing Life alum Italia Ricci has joined the cast of CBS’ freshman superhero drama Supergirl in a recurring role. She will play Siobhan Smythe, Cat Grant’s latest hire who at first becomes a work nemesis for Kara (Melissa Benoist). But she later proves a more deadly foe for Supergirl when she takes on the mantle of the DC Comics villain Silver Banshee.

Supergirl, which launched to overwhelmingly positive reviews, recently was given a seven-episode pickup, bringing its freshman run to 20 episodes.

Ricci is repped by ICM, Protégé Entertainment, Coast to Coast, and Felker, Toczek, Suddleson LLP.
