Universal Studios's dinosaur saga "Jurassic World" has crossed the $1 billion mark at the international box office, becoming the fourth movie ever to achieve the milestone, joining films like "Avatar" ($2.027 billion), "Titanic" ($1.528 billion) and Universal's own "Furious 7" ($1.162 billion), which crossed $1 billion in April this year.

"Jurassic World" became the third-biggest film in terms of worldwide grosses, earning $647.5 million in North America and $1.64 billion worldwide, behind "Avatar" at $2.79 billion and "Titanic" at 2.19 billion, according to The Wrap. 

Universal announced on Sunday that the studio had crossed $6 billion in global box office receipts, which includes $2.157 billion domestically and $3.886 internationally. Last month, the studio surpassed Fox to break the industry record for worldwide grosses in a year of $5.53 billion.

The movie, starring Chris Pratt and Bryce Dallas Howard, had the biggest opening weekend at the international, domestic and worldwide box offices, grossing $523.7 million in total. The film also went down in record books as the fastest movie to cross $1 billion worldwide (13 days).

Universal has become the first studio ever to have three films gross $1 billion at the worldwide box office within a single year with "Jurassic World," "Furious 7" and "Minions," Deadline reported.

Duncan Clark, president of distribution for Universal Pictures International, said the reason behind "Jurassic World's" success is "exceptional word of mouth."

"When we opened the film, we never expected to get to $1 billion but we knew we had the goods along with tremendous support from marketing and filmmakers who gave us everything," he said, according to Variety. "It became a movie for teens and the entire family in every country."
