The Jurassic Park franchise has always featured humans going up against dinosaurs (most frequently the Tyrannosaurus Rex and/or Velociraptors) as a way of emphasising just how out of place the creatures are in our world and how dangerous their presence here is. However, with the Indominus Rex set to serve as Jurassic World's "big bad", it appears as if this movie is shaking things up a little. Apparently, there will be a trained T-Rex (muzzled for most of the movie apparently) which at some point goes into battle for Chris Pratt's trainer against the out of control I-Rex. That sounds like one hell of an epic fight scene!
