The average US cinema ticket costs $8.17. That's almost double what it would have cost to see the first of the Jurassic series, Jurassic Park, on its release in 1993.
Adjusting for inflation, Jurassic World was actually only the third-biggest film, in terms of box office takings on its opening weekend, according to movie budget experts at the-numbers.com.
In second place is Spider-Man 3, which took $382m internationally when it opened in 2007, the equivalent of about $543m today.
The top spot goes to Harry Potter and the Deathly Hallows, Part 2. This, the final Potter film, took $483m in its opening weekend in 2011, equivalent to $554m today.
It's notable that none of the top 10 are original films.
"I think you might see a pattern here. We've got sequels and reboots and re-imaginings," says Symonton. "People are going to see 'event' films, and they certainly saw Jurassic World harking back to a franchise that people really loved."
He says the popularity of sequels is a big influence on creative decisions in Hollywood.
"Studios tend to put their massive production budgets behind things they feel are safe. When you've got a well known, established franchise, you may not even do that well domestically in North America, but you're definitely going to repay your investors internationally."
