Following KOTTER, Hegyes appeared on CAGNEY & LACEY, then continued to act on television, mostly in guest-starring roles including NEWSRADIO, DIAGNOSIS MURDER and THE DREW CAREY SHOW. He made occasional films, including Bob Roberts with Tim Robbins.
In 1985 he played one of the Vipers (Pete's gang) on DAYS OF OUR LIVES.
A longtime resident of Venice, California, he brought the city to the internet in the web series THE VENICE WALK.
Hegyes also taught at Brooks College of Long Beach and wrote screenplays. Peter Loewy, who runs the Forum Theatre Arts Center in Metuchen, says he planned to work with Hegyes on a one-man show a year or so ago, but Hegyes' health problems -- he needed a hip replacement, among other things -- put it on hold indefinitely. "He was a gentle guy," Loewy remembers. "He had, ironically, a big heart."
