The Dolby Theater and Ballroom were transformed into Jurassic World for Universal Pictures and Amblin Entertainment’s BIG movie premiere this week. Everyone from the mega-movie hit the carpet from Bryce Dallas Howard to the film’s consulting paleontologist (um, doesn’t every picture have one?) Jack Horner. Superstar Horner had even presented a talk at the Natural History Museum earlier in the day. After the movie roared onscreen, Chris Pratt hit the stage with Jimmy Buffett to help him sing “Margaritaville.” Adorable couple alert: How cute are Pratt and Anna Farris? And Joe Manganiello and Sofia Vergara? Forgetaboutit. Jurassic World opened today.
