Fans might recognize the voice of Ellen McLain, who uses the same voice of GLaDOS (from the Portal video game series) for the A.I. on board the Jaegers from the first Pacific Rim. The film's cast includes John Boyega, Scott Eastwood, Cailee Spaeney, Jing Tian, Rinko Kikuchi, Charlie Day, Burn Gorman, Levi Meaden, Adria Arjona, Karan Brar, and Nick E. Tarabay.
There was a time it seemed Pacific Rim, despite being an instant fan-favorite, wouldn't actually get a sequel. It didn't have the biggest box office in blockbuster history and the world's creator, Guillermo del Toro, has been reduced to story and producer credits.
Boyega looks great in the brief shot, but this is Pacific Rim, so you're not really here for that.
Alongside the teaser somes the message, 'A new generation of Jaeger Pilots will stand tall for all humanity. You're here for the giant robots (i.e., Jaegers). John Boyega is portraying Jake Pentecost, the son of Idris Elba's character in the first film, Stacker Pentecost. Part of the GoJaeger.com viral site, it's an in-universe advertisement for the benefits of the Jaegers. Uprising is indeed coming, and now we have the teaser trailer to prove it.
What's attention-getting, though, is the implication that the Jaeger corps is in need of new pilots.
