Jurassic World star Chris Pratt falls victim to perfect prank

It would appear the countless hours spent on the set of Jurassic World were not enough to prepare Chris Pratt for an epic dinosaur prank.

Famed pranksters SA Wardega dressed up in convincing dinosaur costumes and lay in wait for the actor, who was walking along a corridor when they suddenly jumped out at him.

Pratt is seen jumping back against a door and then sinking to the floor before blurting out a string of expletives.

He later notices the cameras.

“You got me man, that was good,” Pratt said.

In the film, Pratt plays the role of Owen Grady - an experienced velociraptor trainer.
