Laura Vandervoort, who played Kara/Supergirl on the long-running hit drama series Smallville, has been tapped for the recurring role of Indigo. The character is described by producers as a living, strong-willed supercomputer. She was sentenced to Fort Rozz after turning against the people of Krypton. Now on Earth, Indigo will let nothing stand in her way.

In additional casting news, Jeff Branson (The Young and the Restless) has been cast in the recurring role of Master Jailer.
