'Gotham' season 4 casts creepy Professor Pyg; watch the newest trailer

Fox’s “Gotham” is about to introduce a new villain. It looks like things are about to get more interesting with the help of an award-winning veteran.

Michael Cerveris will be joining the show this upcoming season. His TV credits include “Fringe,” where he played the Observer named September, “The Good Wife” and “The Tick.” Cerveris will be bringing Batman villain Pyg to life in the fourth season.

Executive producer of “Gotham” Danny Cannon earlier revealed that Cerveris is actually one of his best friends. “He was in my film school graduation movie when we were both amateurs, and now he’s joining the fold as Professor Pyg.” Cerveris is expected to play the villain in an arc that would span several episodes.

According to comic book lore, Pyg, whose real name is Lazlo Valentine, is a schizophrenic who wears a pig mask, notes TV Line. He is the leader of Circus of Strange and has calling cards that include a small army of "Dollotrons." If the show stays faithful to the source for this particular arc, things could get more twisted than ever.

After Lee left town and Jim Gordon at the end of the third season, sources say he will be going through a dark path. Recently, an image of what appears to be Jim’s latest girlfriend, Sofia Falcone, has surfaced. She will be played by “Teen Wolf” star Crystal Reed. She happens to be Don Falcone’s daughter, which means she will be causing trouble this season.

Viewers can expect Jim Gordon to make big steps as he tries to vie for Commissioner. However, everyone can expect Gordon to save the city from the big bads that will be introduced.

“Gotham” will return for season 4 in September 21 on FOX. In Australia, it will air on Syfy.
