Total Copies Sold: 2,893,063 Most finales have to really amp up the sentimentality to get audiences ready for a big ending, but with fans having invested ten years over seven films Harry Potter had that already sorted. Although the marketing pushed it, much of the emotion of the series ending came naturally from those who'd grown up with the series and mere just making the shift into adulthood. Selling only slightly more Blu-Ray copies than The Half-Blood Prince, we have to assume that the film was stopped from hitting even bigger numbers due to The Complete Collection's release around the same time; it hasn't left the bestsellers list on Amazon in years.
