"Jurassic World" teaser, the first to feature the film's cast, hit the web. Bryce Dallas Howard and Chris Pratt appear as the theme park's staff, with her throwing a worried look at him. The teaser also pays tribute to Steven Spielberg's "Jurassic Park" film by using a version of John Williams' original theme song, AceShowbiz said.

"Jurassic World" is set 22 years after the events in 1993's "Jurassic Park". Hapless humans once again are pitted against dinosaurs created from ancient strands of DNA. Colin Trevorrow directed from a script he wrote with Derek Connolly. It will hit U.S. theaters June 12, 2015.

Trevorrow said previously that the film might spawn a sequel. "We wanted to create something that would be a little bit less arbitrary and episodic, and something that could potentially arc into a series that would feel like a complete story," he said.
