"Jurassic World" is the most popular movie in America, starring Chris Pratt who is one of the hottest stars in the country.  If you've seen the movie, you know that he does a great job acting like he's having intense moments with dinosaurs.

After watching this video, I think he may have not been acting at all.

Watch as Chris Pratt as he's the subject of a practical joke involving a surprise visit by a couple of pretty realistic dinosaurs.  I think he handled it very well, whereas I would've screamed like a seven year-old girl at a One Direction concert.
