These are the weekends that record-breaking summers are made of.

The North American box office sizzled as Disney and Pixar’s “Inside Out” and Universal’s “Jurassic World” duked it out at the multiplexes. After shattering records for domestic and international debuts, “Jurassic World” became only the second film in history to top $100 million in two separate weekends.

The dinosaur sequel nabbed first place with a massive $102 million, pushing its domestic total to $398.2 million. “Jurassic World” has now passed “Jurassic Park” ($357.1 million) as the highest-grossing domestic release in the franchise’s history when not adjusted for inflation.

Its dominance ended one of the most remarkable winning streaks in cinema history, putting a period to Pixar’s run of first-place finishes. Every previous film released by the studio bowed in the top spot on domestic charts.

Not that Disney is complaining. Buoyed by rapturous critical notices, “Inside Out” scored the second best debut ever for Pixar, behind only “Toy Story 3’s” $110.3 million opening, and the highest opening weekend ever for an original, non-sequel property, passing “Avatar’s” $77 million start. The brainy family film picked up $91 million from 3,946 playdates. That was a significant jump on the $60 million-plus opening that Disney had projected for “Inside Out.”

“Inside Out,” which unfolds largely inside the mind of a young girl struggling to come to terms with her family’s move to San Francisco, represented a big gamble for Pixar. Produced for $175 million, it had a concept that defied an easy sales pitch and could have gone soaring over the heads of younger moviegoers. Instead, critics praised the film as ranking alongside such previous Pixar greats as “Up” and “Wall-E” in pairing cinematic daring with emotional uplift.

Disney’s distribution chief Dave Hollis praised the studio’s marketing team for conveying the twisty concept in a series of upbeat ads and for getting the word out early that the picture was not to be missed. “Inside Out” first screened for movie theater owners and press at CinemaCon in April and followed that up with a high-profile premiere at the Cannes Film Festival.

“There was a critical mass building of people saying, ‘Wow, it’s so original, it’s Pixar doing what Pixar does best,'” said Hollis. “That critical mass tipped over into the consumer mindset.”

Analysts argue that the positive response was one of the major reasons “Inside Out,” like “Jurassic World” before it, soared past projections.

“This is another example of word of mouth spreading fast for a movie and people getting behind in a big way,” said Phil Contrino, vice president and chief analyst at BoxOffice.com.

It wasn’t just reviews. Production delays on “The Good Dinosaur” forced Pixar to abandon its original 2014 release date, putting a two-year gap between the animation studio’s films and driving interest in its latest title.

“It speaks to the power of Pixar,” said Jeff Bock, an analyst with Exhibitor Relations. “Audiences see that name and they know it stands for quality. You can’t say that about any other company that does animation. They’re more hit and miss.”

Opening weekend crowds for “Inside Out” were 56% female and 38% under the age of 12. Families comprised 71% of the audience.

There was one casualty at the box office. Open Road’s “Dope” did not perform as well as the studio had hoped. The Sundance Film Festival favorite sparked a bidding war when it debuted in Park City, but the picture’s offbeat sensibility (it’s a comedy about nerds living in South Central) was difficult to convey to audiences. “Dope” pulled in a disappointing $6 million from 2,002 locations, good enough for a fifth place finish.

Open Road chief marketing officer Jason Cassidy noted that the film played well with critics and audiences, which could help it “leg it out” in coming weeks.

“When you have two movies doing almost $200 million in the marketplace, it’s tough for much else to cut through,” said Cassidy. “The great news is we have a great movie that plays great.”

In third place, Fox’s “Spy” showed some staying power, slipping 29% in its third weekend to $10.5 million and bringing its Stateside total to $74.4 million. Disaster film “San Andreas” nabbed the fourth position on charts after snagging $8.2 million and pushing its domestic haul to $132.2 million.

Among arthouse releases, new indie distributor the Orchard kicked off the sex comedy “The Overnight” to an estimated $61,523 this weekend on three screens in New York and Los Angeles, for a per-screen average of $20,507. The company plans to expand the film next weekend and will have it playing on more than 300 screens by the July 4th holiday.

In its second weekend, “Me and Earl and the Dying Girl” expanded from 15 locations to 68 theaters, bringing in $351,678. The dramedy about a young cinephile who befriends his critically ill high school classmate has earned $645,090 so far.

Final numbers have yet to be calculated, but the overall box office will annihilate the figures put up a year ago when “Think Like a Man Too” and “Jersey Boys” opened.

“This is an example of the market expanding when it needs to accommodate two big movies,” said Contrino.
