Just out of curiosity, Ghost has overtaken Power Rangers in less than half that time, had a an international opening stronger or comparable to Ant-Man and will probably make twice or three times as much money as Power Rangers by only costing 10 millions more.
Power Rangers is a way more popular IP world wide, had similar or better reviews and no controversy and still made a third of the money on the international market. But somehow Ghost is the bomb, Scarlett has no star power. Which somehow is strange, when a live action anime can have the same numbers as Ant-Man. For example theaters around here are still very well booked with Ghost, while Power Rangers lost its audience in the first week. And Power Rangers is on TV for 20 years already around here, still Ghost blow it out of the water pretty much everywhere expect the US.
So if Ghost is a bomb, is Power Rangers a disaster of apocalyptic proportions? Also Ghost has past Ghostbusters on the international market probably by the end of the week.
I left this post alone earlier, because I was on my phone.
I'm curious where you are getting the Ant-Man comparison from though. Ghost in the Shell won't end up anywhere near Ant-Man overseas. That film finished with almost $340M in foreign gross.
On the surface, GitS' second weekend take overseas looks pretty good. However, $21.3M of that was China, so we're really looking at $20M for the remaining overseas territories. The film also opened in Japan ($3.2M estimate), India, and a handful of small territories this weekend. Given that last weekend was $40M overseas, that means that the holdover territories had a similar 60% drop to the domestic box office take.
Ghost in the Shell has no more major openings left ahead of it, and is showing poor legs. Given that Fate of the Furious is opening next weekend, it is also expected to have a rapid drop off in China (which was fueling this weekend's box office). If the film manages to avoid a total collapse elsewhere, you might end up with a $200M worldwide box office finish.
It will not finish with 2-3x the gross that Power Rangers manages worldwide. Power Rangers still has South Korea, China, and Japan left to open with, so even with modest grosses in all three, it has a decent shot at $150M+ when you factor in holdover business. Furthermore, if we are approaching this from a financial standpoint, Power Rangers will end up with about twice as much domestically as GitS will. As mentioned in the article about China I linked above, Domestic gross is still the most important factor.
On top of all of the above, Power Rangers wasn't really a success story, so I'm not sure why that is your measuring stick. It made enough for Lionsgate to offset their personal costs, but the overseas performance will do further damage to their ability to pre-sell larger films going forward.
