Born as Marcie Virginia Hunt in Chicago, Illinois, her acting career stretches back to 1935, but in the 1950s she and her husband Robert Presnell were blacklisted, making finding work difficult. Her role in Star Trek was her last until her appearance in the drama Chloe's Prayer in 2006. In 2008 she appeared in the short crime film The Grand Inquisitor and in the television movie Meurtres à l'Empire State Building. Hunt is also the honorary mayor of Sherman Oaks, California.
