Actor Tyler James Williams has been added to the cast of post-apocalyptic horror drama TV series 'The Walking Dead'. Williams will play a character called Noah, although the exact details are being kept under wraps, according to The Hollywood Reporter. It is not currently clear whether the 21-year-old actor will appear in the AMC zombie drama on a guest, recurring or regular basis. Noah is not a character featured in Robert Kirkman's Walking Dead comics. Williams joins the likes of Seth Gilliam for season five of the hit series, while Andrew J West, Alanna Masterson and Christian Serratos are promoted to regulars. It was confirmed earlier this month that the long-planned 'Walking Dead' spin-off has been given a pilot order by AMC. 'The Walking Dead' season five begins on October 12.
