Batman's record stood until it was beaten three years later, in 1992, by its own sequel, Batman Returns, which brought in $45.7 million over its opening weekend.
That record only stood a year, however, when it was beaten by Jurassic Park's $47 million opening weekend in 1993.
But the Caped Crusader wasn't done, yet...
The franchise swept back into first place in 1995 with Batman Forever's $52.8 million opening weekend - the first movie to ever gross north of $50 million in its opening frame.
At which point Steven Spielberg and his dinosaurs looked at the situation and said, "hold my beer..."
Jurassic Park's sequel, The Lost World, crushed Batman Forever's record for best opening weekend with $72 million in 1997, seemingly ending all doubt over who reigned supreme at the domestic box office.
But the World's Greatest Detective had one swing left...
DC and WB teamed him with his sidekick to release Batman and Robin just 4 weeks after The Lost World took the All-Time Opening Weekend crown...
And the result?
...a disappointing $42.9 million opening.
Leaving Spielberg and his Michael Crichton adaptation with the All-Time record well into the millennium, and paving the way for future record-setters such as Harry Potter, Spider-Man, and Pirates of the Caribbean...
But Batman would return!
In 2008, Gotham's masked vigilante ascended the throne once more, with Christopher Nolan's The Dark Knight smashing into the record books with an opening weekend tally of $158 million.
And that's it, right?
Case closed?
In the All-Time Opening Weekend rivalry between Batman and Jurassic Park, Batman had the final say?
No.
In 2015, Spielberg's dinos came roaring back, reclaiming the All-Time Opening Weekend record with Jurassic World's mind-numbing $208 million.
A record so impossible, so insurmountable, so unattainable, that it lasted...
...6 months.
When Star Wars: The Force Awakens was like, "lol, you and Batsy are cute...watch this," and became the new champ with a still-number-1 $248 million, an amount so otherworldly that I honestly have no idea if/when it'll ever be beaten...
...until, maybe, a new Batman/Jurassic movie comes around?
