"We're playing a global box office game now and North America alone isn't the say-all-end-all in the total global picture of box office sales," said Daniel Loria, editorial director of Boxoffice Media.
"Many times what will decide if a sequel happens if a film flops in North America, is how strong it does overseas."
The North American market makes up only about a third of global box office revenue, according to industry estimates. It's still the world's largest film market, but by no means the ultimate arbiter of ticket sales success.
Independence Day: Resurgence, for example, did US $383 million in worldwide sales. More than $280 million of those sales came in foreign markets, $75 million of which came from China and another $6 million from Russia.
The 1996 version of the film was not screened in those countries.
Less than 20 percent of Ghostbusters' revenue came from foreign viewers in 1984. More than 40 percent of the 2016 version's ticket sales have been foreign and $6 million of those sales came from Russia. Neither version of the film was screened in China.
Remakes that might seem stale in North America are fresh to audiences in other countries that haven't seen the original.
Domestically, remakes are known entities. They have inborn marketing advantages, and what's more, they're relatively cheap, analysts say. You don't have to pay a team of writers to start from scratch if you're working on yet another version of Spider-Man.
"There is a reference point. There is a concept already built in," said Paul Dergarabedian, senior media analyst at market research firm comScore.
"There is a way to describe the movie very quickly and that is the easy allure of a remake. That's why a lot of sequels get greenlit as well. On paper at least, you're kinda ahead of the game theoretically."
But that doesn't mean they always work. Studios pick remakes because the original movie brands are popular. What if a new version feels phony to dedicated followers? There's a lot of room to screw up films some people consider iconic.
Studios walk a fine line, analysts say, between enticing viewers with something they haven't seen before and ruining the nostalgia that keeps certain film franchises alive.
The perfect example: Jurassic World, though film aficionados often go to the mat over whether the film is truly a remake.
The 2015 thriller did US $1.67 billion in ticket sales and spawned a new hype for toys, T-shirts and Chris Pratt action figures. It did so well, Universal Pictures has a sequel planned for the summer of 2018. And if that does well, analysts say, there could be a third movie.
Think about it this way: A second and third film based on a remake of a 20-year-old movie property exist based on the success of an existing brand. They'll all do well at the box office because of that brand and will displace other movies that may have been made because of that brand.
Film studios look at that formula, and make up their minds pretty quickly that remakes are smart business, said Bruce Nash, founder and publisher of The Numbers, a box office tracking and film industry analysis website. It's like producing one film for the price of three, if you factor in all the advertising the first movie does for the rest of the series.
And if a remake bombs - and they often do; just look at Ben-Hur or 2011's Conan the Barbarian - studios write them off, scrap the rest of the series and pick up another script.
Remakes and reboots make those second, third and fourth films a safer bet, analysts say, but you still have to make a good movie, or audiences won't show up.
And sure, viewers will grumble as they watch trailers that nothing new is coming out of Hollywood, but they'll also spend money on tickets to the next instalment of Star Wars.
That's hundreds of millions of dollars coming pretty easily to studios. They'll take that deal, analysts say, even if it looks eerily familiar.
