Dwayne Johnson, aka The Rock, has been named the highest-grossing actor in Hollywood.

Johnson has toppled Robert Downey Jr. from the top-spot on Forbes' new list for 2013.

The buff star's vehicles, including Snitch, G.I. Joe: Retaliation, Fast & Furious and Pain & Gain, took in a combined $1.3 billion in global ticket sales.

Downey Jr. came in a close second, despite starring in Iron Man 3, which was the top-earning movie of 2013, raking in $1.2 billion.

However, that was Downey Jr's only movie of the year, while Johnson starred in four hugely commercially successful films.

Johnson is expected to have another big year in 2014 with starring roles in the next instalment of Fast & Furious as well as Brett Ratner's Hercules.
