Character actor Vincent Curatola made a name for himself as a New York mob underboss on one of the most acclaimed crime dramas in the history of cable television, "The Sopranos" (HBO, 1999-2007). Entering the highly competitive profession of acting relatively late in life, Curatola invested himself in the craft with acting classes and roles in several off-Broadway productions. Early guest turns on police procedurals like "Law & Order" (NBC, 1990-2010) and the spin-off TV movie "Exiled" (NBC, 1998) paved the way for Curatola's big breakthrough on "The Sopranos." As the ambitious crime family second-in-command Johnny "Sack" Sacramoni, Curatola deftly portrayed a complex character in a role that could have easily been two-dimensional. Johnny Sack's rise to power and eventual decline provided the show with some of its most intricate plot developments, and his volatile relationship with New Jersey capo Tony Soprano (James Gandolfini) gave audiences several of the venerated series' more intense exchanges. Having enjoyed strong notices for his work, the actor also appeared in such projects as the comedy feature "Fun with Dick and Jane" (2005) and the short-lived metaphysical police drama "Life on Mars" (ABC, 2008-09). Although always reliable in the role of a "made guy," Curatola elevated his characters beyond the usual mob caricature with thoughtful, multi-layered performances.
