The actor has taken on the part of Father Guidotti, a Catholic priest who presides over the upcoming nuptials of Vanessa Villante (Alin Sumarwata) and Lucas Fitzgerald (Scott Major).
Pictured: John Orcsik as Father Guidotti in Neighbours.
Although parents-to-be Vanessa and Lucas are not an item, a new storyline sees them planning a sham wedding to impress Vanessa's overbearing mother Francesca.
Father Guidotti's first scenes see him summoned by Francesca (Carmelina di Guglielmo) to provide guidance to the bride and groom ahead of their big day.
Orcsik said of the role: "He is a pretty liberal-minded priest, which is just as well considering what is about to transpire!"
The 67-year-old played Mike Georgiou on Cop Shop in the late '70s and early '80s, while he also had a recurring guest part on Neighbours from 1998 to 2002 as Drew Kirk's father Ron.
Father Guidotti makes his first appearance on Australian screens next Wednesday (October 31) and on November 28 in the UK. Get the Inside Soap magazine on your iPhone or iPad
