Raul Castillo is about to show his bad side…

The 38-year-old Mexican American actor has been cast as DC Comics villain Eduardo Flamingo on Fox’s Gotham.

Making his debut in episode nine of season two, Eduardo Flamingo is one of Gotham’s most dangerous hitmen. Killing for him isn’t just a job, it’s an art form. Armed with a spiked chain and an appetite for flesh, this rock-a-billy assassin will prove to be one of Detective Jim Gordon’s (Ben McKenzie) trickiest foes.

Castillo, who starred on HBO’s Looking, was just named one of Variety Latino‘s 10 Latinos to Watch, and will next be seen in HBO’s Looking special, which will wrap up the recently cancelled series, and the Netflix original movie Special Correspondents, written and directed by Ricky Gervais.

He recently completed production on the independent films Staring in the Sun and Sweets and will co-star in two additional independent films, Celestina and Finding Albie Finch.
