Joyce King (full name Kathryn Joyce King) worked as script supervisor, but also occasionally as stunt double and small part actress, on small and large Hollywood productions from 1957 to the late 1990s. Her first job was as script supervisor for Burt Topper on his debut low-budget film "Hell Squad", which was released in 1958, and her last was as script supervisor for a 1997 episode of the TV series "JAG".
There's a long interview with her in Brian Albright's 2008 book "Wild Beyond Belief!: Interviews with Exploitation Filmmakers of the 1960s and 1970s" (searchable on Google Books).
