He's not in Pawnee, Indiana anymore! Chris Pratt leads Bryce Dallas Howard and others in an evacuation in the first trailer for the upcoming, highly anticipated film Jurassic World. Universal Pictures, in a surprising twist, released the new footage two days ahead of its planned Thanksgiving Day debut. (A 20-second teaser for the trailer was released on Monday.)

"I'm really proud of you for going on this trip. You're going to have so much fun," Judy Greer's park visitor character says to a little boy in the clip. She teases: "And remember, something chases you, run."

Please do. The boy appears to be on a class trip to Jurassic Park, and is greeted by its famous gate. What starts as a tourist-filled attraction, however, becomes a bloody, hybrid nightmare.

"You just went and made a new dinosaur? Probably not a good idea," Pratt's Owen says. "She's a highly intelligent animal. She'll kill whatever moves."

Jurassic World hits theaters on June 12, 2015.
