(written from a Production point of view)
Mary Kay Adams (born 12 September 1962; age 59) played Grilka in the Star Trek: Deep Space Nine third and fifth season episodes "The House of Quark" and "Looking for par'Mach in All the Wrong Places". She is a descendant of US Presidents John Adams and John Quincy Adams.
Adams also auditioned for the role of Chalan Aroya. Adams also played the role of Na'Toth on Babylon 5 during that show's second season, taking over the role from fellow DS9 guest star Caitlin Brown. Although she was listed in the show's opening credits for the entire season, she only appeared in two episodes. Mostly, she worked with Andreas Katsulas on the show.
Adams commented: "Actors I am close to who have done these shows all agree that Star Trek is fabulous because it's the closest thing to playing classical theater..It's very archetypal, it's very Shakespearean in its scope. All the aliens are of heroic proportions. Plus you're given direction to be bigger, to be stronger, to fill the makeup. The makeup does a lot of the work for you, but you have to find the balance of matching it somehow".
