Ellen McLain, the voice of GLaDOS, the passive-aggressive AI in Portal (2007 AIAS Interactive Achievement Award for Outstanding Achievement in Character Performance) and Portal 2, (2011 Spike Video Game Award in the category "Best Performance by a Human Female") is also the voice of Gipsy Danger in Guillermo del Toro’s film, Pacific Rim. Her work as GLaDOS also appears in Lego Dimensions, and she sings the new Jonathan Coulton song, “You Wouldn’t Know”.
Ellen has worked in theater and opera for over thirty years. Her professional career began on Broadway with Rex Harrison in My Fair Lady and with the legendary Peggy Lee in her show, Peg. Ellen’s credits range from Linda Loman in Death of a Salesman to Mimi in La Boheme. McLain provides voices for many characters in several video games from Valve. Among them are the Administrator in Team Fortress 2, and the voice of the Combine Overwatch for the Half-Life 2 series. She also voices Broodmother and Death Prophet for DOTA 2. McLain is the only person to have her voice in all the games in The Orange Box.
She sang the ending credits song to Portal, "Still Alive", and Portal 2, "Want You Gone", both written by Jonathan Coulton, and Ellen sang all the voices in the Turret Opera “Cara Mia Addio” by Mike Morasky featured at the end of Portal 2. McLain lives in Seattle with her husband, fellow voice actor and author, John Patrick Lowrie, who insisted she get a voice demo for years and is therefore responsible for her subsequent fame as the much loved and hated GLaDOS.
