Amazon's Zombieland TV series added yet another cast member today, with Switched at Birth star Maiara Walsh signing on to portray the female lead Wichita.

We reported last week that Tyler Ross and Izabela Vidovic joined the cast as Columbus and Little Rock. The only main roles left to be cast are Tallahassee, who was portrayed by Woody Harrelson in the 2009 action-comedy Zombieland, and new characters Fred and Ainsley, two office workers who had a previous encounter with Tallahassee. Emma Stone originally portrayed the con-artist Wichita in the Zombieland movie, which also starred Jesse Eisenberg as Columbus and Abigail Breslin as Wichita's sister Little Rock.

Rhett Reese and Paul Wernick wrote the pilot script and will executive produce with Gavin Polone and Sony Pictures Television. If the series is picked up, it will air on Amazon's Instant Video streaming service. No production schedule was given.
