Movies that make a lot of money often change their budgets to take advantage of international markets. Here are some key points to understand:

• International Earnings: For some films, around 70% of the money made at the box office comes from countries outside the U.S.
• Smart Marketing: Movies like "Avatar" earned over $2.8 billion around the world. They spent extra money on marketing to reach different audiences.
• Language Changes: Adding voice-overs or subtitles to a movie can cost up to $10 million.

This careful planning helps movies make a profit. It allows them to earn more than their production budgets, which are often over $100 million.
