Marco arrived in Llanview as a low-life pimp and pornographer who was only supposed to last for 8 days, but Anthony's offbeat look as well as his impassioned performances and electric chemistry with co-star Judith Light (Karen Wolek) made him such a fan favorite that only a few months after producers killed off Marco in 1978 they revealed the real victim was Marco's heretofore unknown brother, Mario Corelli.
Anthony was nominated for a Daytime Emmy Award for the role in 1982,[4] and won for Marco on General Hospital in 1993.
Anthony was married to his One Life to Live co-star Brynn Thayer from 1981 to 1983.
In 1982 Anthony was nominated for a Daytime Emmy Award for the role of Marco Dane on One Life to Live.
In 1993 he won a Daytime Emmy Award for the role of Marco Dane but for his portrayal of the character on One Life to Live's sister soap General Hospital.
