Think you know all the iconic characters appearing in Fox’s Gotham? Think again!

EW has learned the eagerly awaited Batman prequel series has also cast an actor as Edward Nygma (the future Riddler). Cory Michael Smith has landed the hot role. He’s tagged as guest star in the pilot with an option to expand into a series regular.

In the Fox project from showrunner Bruno Heller (Rome), Nygma is a brilliant young forensic scientist working for Gotham PD and a penchant for speaking in … rather cryptic language. Inquisitive, eccentric and outgoing — yet socially awkward — he wants to be liked, but he doesn’t quite know how.
