In less than one month, Jurassic Park fans will get to revisit Isla Nublar when Jurassic World hits theaters on June 12. To get fans ready for this epic adventure, Universal Pictures has released the first in a series of "video journals" from the set, where Chris Pratt takes us through his elaborate procedure of warming up for his stunt sequences. This 90-second video offers plenty of behind-the-scenes footage, along with Chris Pratt's hilarious antics on set.

The video also shows the cast and crew reacting to Chris Pratt' antics, such as one scene where the actor explains an elaborate (yet likely fake) stunt that he is about to pull off, as Bryce Dallas Howard is seen laughing in the background. The story is set twenty-two years after the events of Jurassic Park, and Isla Nublar now features a fully functioning dinosaur theme park as originally envisioned by John Hammond. After 10 years of operation and visitor rates declining, in order to fulfill a corporate mandate, a new attraction is created to re-spark visitor's interest, which backfires horribly.

In addition to this behind-the-scenes preview, Universal has also unleashed a new TV spot for director Colin Trevorrow's action-adventure. Judy Greer, Vincent D'Onofrio, Jake Johnson, Ty Simpkins, Nick Robinson, Katie McGrath, Lauren Lapkus and B.D. Wong round out the supporting cast for Jurassic World, arriving in theaters June 12. Take a look at the new preview and TV spot below to prepare yourself for Jurassic World.
