Du Quoin actor Brian Gant on tonight's episode of NBC's 'Grimm'

Du Quoin actor Brian Gant, who has guest-starred on television series like "Law & Order," makes a guest appearance on tonight's Episode 20, second season of the NBC television series "Grimm."

The episode airs at 9 p.m. (central time) over local NBC affiliates.

"Grimm" is a combination crime/fantasy series and Brian will have the role of "Anton." The show also guest stars Nora Zehetner from "Heroes."

"Grimm" is a drama series inspired by the classic Grimm Brothers' Fairy Tales. After Portland Homicide Detective Nick Burkhardt (David Giuntoli, "Turn the Beat Around") discovers he's descended from an elite line of criminal profilers known as "Grimms," he increasingly finds his responsibilities as a detective at odds with his new responsibilities as a "Grimm."

His attempts to shield his fiance, Juliette Silverton (Bitsie Tulloch, "The Artist"), and his partner, Hank Griffin (Russell Hornsby, "Lincoln Heights"), from the hazards of his new life have reached a crisis, leaving Juliette in a mysterious coma and Hank on the verge of a mental breakdown.

With help from his confidants, Monroe (Silas Weir Mitchell) and Rosalee (Bree Turner, "The Ugly Truth") - both reformed Grimm creatures, Nick must help those closest to him while still facing off against all manner of ancient evils, including royal lines dating back to the original profilers themselves, the Grimm Brothers.

Tonight, Nick (David Giuntoli) discovers a muse-like Wesen (guest star Nora Zehetner) with the ability to influence those she gets close to - some with positive results, others with terrifying ones. Nick must find a way to get close without losing himself in the process. Juliette (Bitsie Tulloch) arranges a dinner date with Nick in the hopes of clearing the air, but their plans go awry as the case intensifies.
