I can't remember where I heard this rumour, but someone mentioned to me that the GlaDOS-esque voice in Pacific Rim, voiced by Ellen McLain the same voice actress, was going to be replaced after everyone made a big fuss. But new footage of Guillermo del Toro's upcoming monster-mech monstrosity has been released and GlaDOS is still there! (Also: the movie still looks great).
I'm a sucker for mech movies/anime. I'm also a sucker for movies that clearly have a video game influence. Pacific Rim hits a bullseye on both these targets. Also -- del Toro is awesome. I'm hyped for this one.
