“For me, the biggest challenge is to not be goofy, because it’s my natural instinct to be a goofball,” says Pratt. “Before every take, I would have to do this little ritual to be like, ‘Don’t turn into a dumbass halfway through this take!’”

Twenty-two years after the events of Jurassic Park, The Jurassic World theme park is open for business. But to keep attendance high, a new attraction is introduced: Idominus Rex, a genetically modified dinosaur with dangerous capabilities. When the massive creature escapes (go figure), chaos erupts on the island, leaving it up to Owen Grady (Pratt) and Claire Dearing (Bryce Dallas Howard) to save the park from destruction.

Jurassic World
is available on Blu-ray, DVD and On Demand Oct. 20.
