The main difference between actors who earn a lot and those who don't is popularity. Famous actors can attract more people to watch their movies, which means they can ask for higher pay. They also get money from ads and endorsements because companies know that many people recognize and like them. So, the more popular you are, the more you can earn.

Actors who have been in the industry longer and have more skills usually earn more. They get better roles and can be part of bigger projects that pay more. Their experience means they can perform better, which makes them more in demand. So, the more experienced and skilled you are, the more likely you are to earn a higher salary.

Actors in big movies or popular TV shows usually earn more than those in smaller projects. If you're in a blockbuster film, you're likely to get a bigger paycheck. Also, actors who work in international films might earn more because those projects have bigger budgets. On the other hand, actors in independent films or local theater usually make less money.

Actors who are well-marketed and have good agents tend to earn more. If you have a strong team promoting you and negotiating your contracts, you can get better roles that pay more. Also, being with a top agency helps because they have the connections to get you into high-paying roles.
