Ellen McLain, the actress that voices GlaDOS

Ellen McLain previously voiced the radio communications dispatcher of the Combine Overwatch throughout the Half-Life 2 saga. The developers of Valve were so impressed with her, that they wanted her for another game and this time she would be given a main role, and that was GlaDOS. Naturally of course she did a fantastic job and got called in for the sequel, which she did an even more fantastic job. Fun fact: She also worked on the Sci-fi blockbuster Pacific Rim as Jaeger A.I.
