Dwayne 'The Rock' Johnson reportedly charges $1million to post about his movies on Instagram, Twitter and Facebook

He is the highest-earning movie star on the planet

The salaries of Hollywood's biggest stars for 2018 were revealed today, with Daniel Craig, Dwayne Johnson, Vin Diesel, Anne Hathaway and Jennifer Lawrence taking home the biggest fees for their movies.

Beyond the usual rankings and gender disparities, the list also throws up a few interesting nuggets on exactly what the stars are being paid for.

In particular, this from Variety stood out:

'Want access to Johnson’s 104 million Instagram followers? It’s going to cost you. The Rampage star is asking for a $1 million social-media fee as part of his package for the upcoming Red Notice; that includes promoting the film on the likes of Twitter and Facebook.'

On the face of it this seems a crazy amount of money to spend on a few tweets and Instagram photos, but when you think that there are more Instagram followers of The Rock than there are people in Canada and the United Kingdom combined, one million is arguably a steal for unfettered access to his legion of potential customers.

Though Daniel Craig will take home the biggest lump sum this year for returning as James Bond, Dwayne Johnson will likely be 2018's highest paid actor due to the volume of movies he cranks out.
