This is supposedly footage from the filming of the new Ghostbusters movie. Except it almost certainly is not. As Ghostbusters 3 is still in the writing stages and it turns out they don't actually make robots in films any more. They just use computers and internets or whatever. I'm hearing it's a viral clip, of which there will be many, for the new Ghostbusters game which looks amazing. The video below is probably the same deal.
