Marciano grew up in New Jersey and has admitted to having a troubled youth, "I was hanging around on street corners, drinking, gambling, playing cards, going to the racetrack, shooting pool, all those kind of things". At the age of seventeen, Marciano was involved in a car crash after a night out partying and was lucky to survive. This prompted him to sort his life out and he enrolled at Northeastern University, Boston to study Biomedical Engineering. After a disappointing start, Marciano transferred to Economics and Accounting for his second year before dropping out to pursue acting.
In 1985, Marciano moved to Los Angeles where he got his big break two years later as a guest star in Wiseguy. More small parts followed until he landed the part of Detective Vecchio in Due South in 1994. He played the part for two seasons before his character was written out, replaced by Detective Stanley Kowalski, due to filming commitments. He returned for the series finale where Vecchio and Kowalski's ex-wife got together.
In 1991 Marciano married Katayoun Amini (who played Vecchio's ex-wife Angie in Due South) and together they have a daughter, Ariana Grace.
