As he's admitted many times, Ritchie Coster's bread and butter characters are gangsters, terrorists, murderers, and all sorts of other traditional bad guys. One of his most well-known roles was in Christopher Nolan's 2008 Batman sequel, "The Dark Knight," which starred Christian Bale as the Caped Crusader, Heath Ledger as the Joker, along with Michael Caine, Maggie Gyllenhaal, Morgan Freeman, and Gary Oldman. During the Joker's rise to power in the movie, he clashes with Gotham City's various criminal gangs, eventually eliminating all of them. Coster's gang leader character was called the Chechen, an associate of Carmine Falcone's who controlled the drug trade.
Some of his other widely seen "heavy" type roles include the terrorist Anslo Garrick on "The Black List," and mob boss Michael Bianchi on "Shades of Blue." He's also appeared on four "Law & Order" series — the original show plus "Special Victims Unit," "Criminal Intent," and "Trial by Jury."
Coster told The Actor's Audience that he enjoys when he's able to branch out and play characters that go against his type, but ultimately if "if the heavy keeps coming my way for the rest of my career, then that's fine, it's still a joy."
