Pacific Rim is a movie made by Guillermo del Toro, yes the same guy who made Hellboy, and whose recent game Insane was cancelled by THQ.
His film is about giant man-made machines taking on ancient monsters who have come from the sea, so it’s basically like war of the titans but a bit more awesome than that.
GLaDOS seems to help the man-made machines but who knows she can even turn on them, but from the trailer they have released you can see that she helps the humans.
Her voice actress is Ellen McLain who speaks through a special filter to achieve GLaDOS’ voice. But since the voice and everything belongs to Valve since the character is their from their IP Portal, del Toro has already taken permission from the company to include her voice in his movie.
He is a fan of Portal, and looks like Valve agreed that this would give GLaDOS more exposure. Check out the trailer below.
