Here's why:
* Box Office Numbers: We only have official box office numbers, which are the number of tickets sold. This doesn't account for people who saw it multiple times, or those who watched it at home later.
* International Release: The movie was released globally, and accurate global numbers can be difficult to track due to variations in reporting.
* Home Video: The movie has been released on DVD, Blu-ray, streaming services, etc. Millions more have seen it at home, making a total viewership number even more elusive.
However, we can get an idea of its popularity:
* "Harry Potter and the Sorcerer's Stone" was a massive box office hit, earning over $974 million worldwide. This makes it one of the highest-grossing films of all time.
* The film's success launched the entire "Harry Potter" franchise, which has become a global phenomenon. It's safe to say that hundreds of millions of people have seen the movie in various formats.
While we can't give an exact number, it's clear that "Harry Potter and the Sorcerer's Stone" has been seen by a truly massive audience worldwide.
