Determining the "biggest hit movie" is subjective and depends on how you define "hit." It could be based on:
- Worldwide Gross Revenue: In this case, the biggest hit is Avatar (2009), which has grossed over $2.92 billion worldwide.
- Ticket Sales: This metric is harder to accurately track across all countries and time periods. However, Gone with the Wind (1939) is often cited as the highest-selling film of all time, adjusted for inflation.
- Cultural Impact: Films like Star Wars (1977), The Godfather (1972), and Citizen Kane (1941) have had a profound influence on filmmaking and pop culture, making them "hits" in a different sense.
Ultimately, the "biggest hit movie" is a matter of perspective. While Avatar currently holds the record for worldwide gross revenue, other films have achieved significant cultural impact and enduring popularity.
