TVLine reports he'll play Smoothie, "a well-dressed mob enforcer and sardonic soulless torturer who claims to take a 'New Age approach' to his work." He's further described as "the Andy Warhol of Death" because of his viciousness, ability to hold on to grudges, lack of empathy and his strict adherence to style.

He's joined by Ritchie Coster ("Blackhat") and Zabryna Guevara ("Gotham") as series regulars. Coster plays Mr. Blue, aka Leonardo Scaramucci, the main villain whose day job is as a wealthy businessman, a facade that keeps his illegal pursuits afloat. Guevara plays beleaguered single mom Amanda Hansen, who has discovered her daughter is missing.

"Happy!" stars "Law & Order: SVU" alum Christopher Meloni as Nick Sax, a former detective who has lost everything and now works as a hitman for the mob. After a hit goes wrong, Nick's life is changed when he starts seeing a tiny blue-winged imaginary horse with an aggressively positive view on life. The show also stars Lili Mirojnick as Detective Meredith McCarthy, described as "a tough homicide detective in a man's world."
