Ever since Jim Carrey scored the first-ever $20m paycheck for The Cable Guy, Hollywood salaries have been spiraling out of control. Actors now have the potential to make $100m and above for single project, which is a quite frankly ridiculous amount of cash. However, the days of A-list stars pocketing a basic salary of $20m and above are on the way out in favor of lower upfront fees and profit participation deals that see them land a substantial amount of cash if the movie is a commercial success. It is this system that has seen Robert Downey Jr. and Dwayne Johnson go from barely a blip on Hollywood's radar to two of the highest-paid actors in the business in less than a decade, while starring roles in blockbuster franchises or pulling double-duty as producer have seen the likes of Chris Hemsworth, Mark Wahlberg and Leonardo DiCaprio rake in big bucks over the last year. With that in mind, this article will count down the ten biggest acting paychecks in Hollywood history. Unsurprisingly, the list features some of the biggest names in the business, all of whom earned big bucks from playing a single character. It is the genres that may surprise you, as these gargantuan paychecks cover the Hollywood spectrum from comic book blockbuster to sentimental drama, with a little sprinkle of sci-fi thrown in for good measure. So read on, and find out just how much these A-list stars have been earning. Were these actors worth the money? Do you think that A-list stars get paid too much?
