Jurassic World Trailer Reveals Mega T-Rex, Explosions, Chris Pratt-Trained Velociraptors

The official trailer for the fourth movie in the Jurassic Park series, Jurassic World, was released today in anticipation of its upcoming June 12 release. The movie stars Chris Pratt as what seems to be a glorified dinosaur zookeeper who's training Velociraptors when a hybrid super-Tyrannosaurus Rex goes rogue. Though the unheralded Colin Trevorrow was tapped to direct, Steven Spielberg is still on board as an executive producer. Overall, we're skeptical. Judge for yourself.
