Chris Pratt plays Velociraptor trainer Owen Grady in the upcoming film “Jurassic World.” The actor reportedly wanted his character to seem real and to accomplish this he did deep research and took training from real-life animal trainers.

“I just want this to be real, no matter who the character is. It’s sometimes tough to create a real relationship between a man and an animated character. There was one guy, his name is Randy Miller. He has a company called Predators in Action. He’s got all kinds of amazing animals. I went to his ranch, hung out with him, spent the day seeing him interact with these animals and this was a big part of creating -- having that clicker and the posture that I adopted. All that stuff was part of the research that I did,” he said during a news conference in Los Angeles, reported Screen Rant.

Pratt’s character is someone who is “deadly serious” and, according to the actor, he will show his lighter side only in scenes with Claire Dearing (Bryce Dallas Howard). The reason for the character's no-nonsense attitude will reportedly be his past. He will be a combat veteran who comes to live on an island to stay away from the world.

“There was a bit of a darkness. This is a guy who’s been through something,” he added. Pratt also revealed that raptors will be shown undergoing training in the film and some of them will kill each other in the process. Animals will be shown sacrificing their life for the sake of the park authorities.
