Louis Herthum

His character Andy Broom in La signora in giallo (1984), was named by the prop department not by the writers. In his first episode as Deputy Andy Broom (Thicker Than Water) the script did not provide a name for the deputy's character. When actor Ron Masak who played Sheriff Mort Metzger realized this, he looked at the name tag Louis had been given by the prop department and called him by that name (Andy) to help establish this new Cabot Cove deputy.
