Watch: 'Jurassic World' actor Chris Pratt freak out over dinosaur prank

American actor Chris Pratt may play dinosaur slayer in the box-office smashing 'Jurassic World' thriller, but prehistoric beasts can still make the actor jump out of his skin.

Playing the macho man on the sets didn't quite prepare him for an epic dinosaur prank he fell victim to. 

Prank team, SA Wardega, of the viral Spider Dog prank decided to give an unsuspecting Chris Pratt a scare and dressed up in convincing dinosaur costumes and waited for the actor, who was walking down the hallway, to arrive so that they could suddenly jump at him.

The 35-year-old clutches his chest with one hand while putting out his other arm to stop the attack.

The actor is seen taking a step back against the door on noticing the first dinosaur with a frightened expression on his face, before sinking on the floor.

Just when he thought it was over, another dinosaur comes charging at him and he starts smiling- but after blurting out few expletives.

After regaining his composure, Chris Pratt too acknowledged how brilliant the costumes were and admitted that he did get scared.

'You got me man, that was good' Pratt told one member of SA Wardega.

The video which was put up on Monday has already amassed 3,316,323 views.
