Jill Sayre (born 6 January 1976; age 49) is an actress and vocalist who played Mardah in the Star Trek: Deep Space Nine third season episode "The Abandoned".
Sayre made her television debut in Hercules and the Amazon Women, the 1994 pilot movie for Hercules: The Legendary Journeys. She was later seen in an episode of Conan the Adventurer and in the 1998 TV movie Legalese. On film, she made her debut with a small role in The Hidden (1987, starring Michael Nouri, William Boyett, and Larry Cedar). This role came after Sayre nearly landed the lead role, which ultimately went to Patricia Arquette, in A Nightmare on Elm Street 3: Dream Warriors. In later years, she has worked only with director Sam Raimi, with small roles in A Simple Plan (1998), Spider-Man (2002, starring Kirsten Dunst, with Tim de Zarn) and Spider-Man 2 (2004, starring Kirsten Dunst, with Donna Murphy, Daniel Dae Kim, Rachelle Roderick, Zachry Rogers and Ella Rogers).
Besides an occasional on-screen appearance, Sayre also works in the automated dialogue replacement (ADR, or "looping") department for films and TV shows. Among the films for which she has provided her looping services are Something's Gotta Give, The Benchwarmers (2006), For Your Consideration (2006), Shrek Forever After (2010), Grown Ups (2010) and Oz the Great and Powerful (2013). She has also supplied voices for TV shows such as 24 and Tru Calling.
