There aren’t a lot of things the internet loves unconditionally, but on that list, right behind cats and bacon, comes the video game Portal. Created by Valve, the series challenges players with mind-bending puzzles while being taunted by a snarky, evil artificial intelligence, known as GLaDOS and voiced by actress Ellen McLain. GLaDOS is so beloved that McLain has been enlisted for no shortage of projects riffing on Portal‘s popularity; just last year, director Guillermo del Toro cast her as the voice of the computer in Pacific Rim.
