Though Chris Pratt was a dinosaurs' tamer in "Jurassic World", he was shocked when he met fake dinosaurs off-screen. In a video posted by SA Wardega on YouTube, the hunky actor showed astonishment as he was a victim of a fake-dinosaur prank.

The video began with a message which read, "Who better to prank with dinosaurs than Chris Pratt, Star of 'Jurassic World'." It then showed the SA Wardega crew setting some cameras at some points where the actor would go through. They also prepared two fake dinosaurs for the prank.

After everything was ready and they got a signal that Pratt was approaching, they hid. The 35-year-old actor was walking through the corridor with his team. While he was having a chit-chat with his assistant, all of sudden a roaring Tyrannosaurus rex quickly came to him. The surprised actor yelled, "Oh s**t!" as he jumped against a door. He then gave his fist to the fake dinosaur while smiling, realizing that the dinosaur wasn't real. Another dinosaur, Velociraptor, came to him but he wasn't surprised at all. He gave a pat on that dinosaur, instead.

"You, mother f**ker," Pratt said to the prankster as he took his breath away. However, the "Guardians of the Galaxy" actor also praised their work for the fake dinosaurs which looked so real. "They look great... Did you make these? What is this? Who are you?" he added. "You scared me. Oh, this is great, you have cameras." SA Wardega introduced themselves as the prankster who posted a clip of giant spider which was actually a dog in a giant spider costume.

Anna Faris' husband also found out that his team was involved in the prank. "Did you know about this?" he asked to his team. His assistant answered, "Yes, sorry Chris."

"Jurassic World" has made a record as the first film to ever cross $500 million in one weekend. The film grossed global a total of $511.8 million. The director, Colin Trevorrow, recently explained a plan to make sequel for the film.
