I guess this are the box office data from the year they were released? Or is in an all times box office, that keeps growing up with each re-release?Also the french wikipedia states 8.9 millions of admissions for OUATITW in Italy (not a huge difference but still a notable one). The source is that website: https://www.jpbox-office.com/fichfilm.php?id=9020 (which gives also numbers for Germany and France for that movie).
The art theater playing the original OUATIA is something I didn't know about also. I thought all Americans would only find about the real version 20 years later through DVD release (? Heard something like that multiple times.
I guess what the DVD granted wasn't "the first time American could access the real OUATIA" but more "easy access for those who aren't actively looking for it or aren't just lucky".
USA (available figures on the same website. Those figures are said as "approximative" as they aren't official data but calculated the same way Stanton did with his figures):Il buono, il brutto, il cattivo 21 271 000 (#11 that year)Per un pugno di Dollari 15 591 000 (#20 that year)Per qualche dollaro in piu 13 761 000 (#20 that year)C' era una volta il West 4 190 000 (#39 that year)Il mio nome e Nessuno 3 081 000 (#31 that year)Once upon a Time in America 1 538 000 (#107 that year)So yeah, of course a box office success on the US market is more profitable than a box office success in France or Germany, but not than in France AND Germany. "The real money" is everywhere as long as there is money.
Yes, I was only asking for the US data. It seems the $ income they used is higher than that from the Variety list.
