'Smallville's Laura Vandervoort Joins CBS' 'Supergirl' as Indigo

During Monday's Television Critics Association press event while on the 'Supergirl' set, producers announced the addition of Smallville's Supergirl, Laura Vandervoort, as DC Comics' Indigo. She'll play a living supercomputer that was sentenced to Fort Rozz for treason and will now wreack havoc on earth. 

Vandervoort played Kara Zor-El on the CW's long-running Superman prequel. She currently plays a female werewolf on SyFy's 'Bitten.' She'll begin her recurring role on 'Supergirl' beginning with episode 15. 

In addition, episode 14 finds Lexi Alexander, director of 'Punisher: War Zone,' taking the helm for Master Jailer's debut played by 'The Young and the Restless' actor Jeff Branson. He'll play a relentless and ruthless jailer from Fort Rozz who's determined to bring in all the escapees by any means necessary. 

Producers have a fondness for incorporting actors who've played a part in the DC Comics live-action past. Helen Slater (1984 "Supergirl" film) and Dean Cain ("Lois & Clark: The New Adventures of Superman" TV series) have appeared as Kara's (Melissa Benoist) foster parents, Eliza and Jeremiah Danvers.

Supergirl airs Mondays at 8 p.m. on CBS.
