When Pacific Rim's latest trailer (above) went out last month, a lot of people thought, "Wait! I know that voice!" And indeed, it sounds like Jax Teller reading from "The Life and Death of Sam Crow" as an enormous sea monster destroys a bridge. Oh yeah, GLaDOS from the Portal series can be heard as well.
That was deliberate, director Guillermo del Toro told the Toronto Sun. While GLaDOS actor Ellen McLain will supply an AI voice in Pacific Rim, she will sound different from the trailer. For that, Del Toro said he specifically wanted GLaDOS' voice running down a power-up checklist before the mechas go out to confront the monsters. He even sought (and received) Valve's permission.
"I wanted very much to have her, because I'm a big Portal fan," he said. In the film, however, "The filter we're using is slightly less GLaDOS. Slightly. The one in the trailer I wanted to be full-on GlaDOS."
