So this one would have made +84M if the exchange rates were the same as they were back then (since it appears it will draw more, it would be an equal percentage above 84M that the total adjusted grosses would be).
I think adjusting for general inflation is a silly measure, but I'm not sure adjusting for currency exchange falls quite in the same category because the cost of the ticket itself isn't affected by that....at least I don't think it is. I'm still thinking this one over.....
I think this would be a good example:
Let's say a chinese movie made 2B chinese yuan in april 2013.
Back then, that was $308M australian dollars, or $322M american dollars.
What if a sequel to that movie came out on december 2016, and it also made 2B chinese yuan(leaving inflation out, so it sold exactly the same amount of tickets)? The exchange rates changed quite a lot since the 1st movie:
If you express it in australian dollars, it made $396M australian dollars.
But if you express it in american dollars, it made $288M american dollars.
So someone in australia would probably think it was much more succesful (it made $88M more right?), while someone in the US would probably think it actually did slightly worse than the original (it made $34M less after all!).
Therefore: if the exchange rates change significantly between movies, comparing foreign box office numbers directly is like comparing apples and oranges.
If you don't know how the exchange rates changed, you don't actually know if a movie drew a bigger audience or not, as the example shows.
From a US studio's point of view, they will make less money OS now, so the studio will make less profit. But that doesn't necessarily mean the movie was less succesful overseas. It just depends on how you define if a movie was more succesful. Is it more succesful if it makes the studio more money, or is it more succesful if more people actually go and see the movie?
