* Salaries: Actors are paid a set salary, which can be very high for a big star like Jim Carrey. This is part of the production budget, not the box office revenue.
* Box Office Revenue: This is the money generated from ticket sales, and it goes to the studio that produced and distributed the film.
* Profit Sharing: Sometimes actors can get a percentage of the profits a film makes after production costs and marketing expenses are covered. This is rarer for established actors, as they typically get high salaries.
* Back-End Deals: These can be negotiated for stars, where they might get a percentage of the film's gross revenue, not just the profits. This is less common than profit sharing.
In short: Jim Carrey doesn't get to keep the box office money. He gets paid a salary for his work, and might have a profit-sharing deal, but the vast majority of the revenue goes to the studio.
