The Rock has replaced Iron Man as the world's highest-paid actor.

Dwayne Johnson has toppled Robert Downey, Jr. as the most in-demand guy in Hollywood, according to Forbes magazine bosses.

The former wrestler hauled in an impressive $64.5 million over the past year thanks to his roles in the Fast & Furious franchise, San Andreas and Central Intelligence, and that's plenty to take the top spot on the new rich list.

In fact, it almost doubled the millions he made the year before.

Johnson took to Twitter to celebrate pole position, writing: "Want to say two things about this. I started w/ (with) $7 bucks (sic). If I can overcome, so can you."

Jackie Chan comes in second on the new Forbes list with an estimated $61 million in earnings for the year, while regular list members Tom Cruise and Johnny Depp also make the top five, banking $53 million and $48 million, respectively.

Depp will take a hit on next year's list after agreeing to settle his divorce from Amber Heard, his wife of 15 months, with a $7 million handout.

Meanwhile, last year's top dog, Downey, Jr., slides to eighth on the new Forbes list, tying Bollywood superstar Shah Rukh Khan with an estimated $33 million.

Johnson looks set to rule the list for some time to come with big roles in the Baywatch and Jumanji revamps and his ongoing part in the Fast & Furious films - he'll reprise his role as government agent Luke Hobbs for the fourth time in 2017's Fast 8.
