Actor Robert Costanzo is generally typecast an urban Italian-American, prone to mouthing such lines as "You gotta problem with that?" Costanzo began popping up with regularity in such films as Saturday Night Fever in the late '70s. The first of his many TV-series stints was as plumber Vincent Pizo, the blue-collar father of Travolta clone Joe Piza (Paul Regina), in 1978's Joe and Valerie. He retained his man-of-the-people veneer as maintenance engineer Hank Sabatino in the weekly series Checking In (1980), Lt. V.T. Krantz in the 1990 TVer Glory Days, and the voice of Detective Bullock in Warner Bros.' Batman: The Animated Series (1992). In 1995, Robert Costanzo joined the cast of television's NYPD Blue as Detective Giardella.
