All of the summer blockbusters are finally giving us big reveals of their baddies, and Jurassic World (in theaters June 12) knew it was due. In the latest trailer we get a little more back story, learning that there was corporate pressure for the genetic medication that led to the new big bad reptile that gets loose and plagues whichever tropical island the film takes place on. Resident dinosaur-scientist B.D. Wong shows up in this clip, humbly bragging that this new beast was made to be bigger than the T-Rex. Ok, but you were there the first time this idea went south. Someone in your shoes should maybe make a personal decision to abstain from any future experiments with dinosaurs. Watch the jaw-snapping, people-eating, Chris Pratt-ing trailer below.
