Gotham isn't done casting its villains just yet. Today, Cory Michael Smith has joined the pilot as The Riddler.

The Batman prequel series will feature Edward Nygma as a brilliant young forensic scientist working for the Gotham PD, and he is known for speaking in a 'rather cryptic language'. The future Riddler is inquisitive, eccentric and outgoing yet socially awkward. He wants to be liked, but doesn't quite know how working alongside Gotham detective Jim Gordon (Ben McKenzie ) and his partner Harvey Bullock (Donal Logue).

Taylor as The Penguin, Camren Bicondova as Selina Kyle (the young Catwoman), and David Mazouz as the very young Bruce Wayne. Not yet cast is The Joker.
