But what propelled him to the pinnacle? The Reporter explains: "A throwback post leads Johnson's charge back to No. 1: a March 1 Instagram photo featuring him as the Incredible Hulk for Halloween, decrying his 'f*cked up haircut' in the picture."
Let that be a lesson for all aspiring actors, I assume. You have to charm your audience constantly with tales of your past, as well as glories of your present and future. Self-deprecation scores bonus points.
Which is odd, as I'm not sure self-deprecation works too well in Hollywood.
The 4 million likes this one Rock-y post achieved made the star ascend to the week's golden statuette status.
Who, though, might be the paper and scissors just behind him on the Hollywood Reporter's Top Actors chart? In second place was Jennifer Lopez, then Zendaya and Lupita Nyong'o. Kevin Hart and Dove Cameron were nipping at their heels.
In seventh place was "Wonder Woman" actor Gal Gadot. She, or perhaps her social media handlers, conjured something revolutionary to leap 18 places from the week before.
"Gadot posted pre-Academy Awards, where she was one of the presenters, on Facebook accompanying a video in which she was getting her makeup done, writing, "Good luck to all the nominees!" says the Reporter.
This apparently sent the metrics soaring.
Please imagine how these stars' handlers now strategize weekly -- or, some might say, weakly -- to be seen and heard around the web.
They used to say you're only as good as your last performance. It seems that these days, you're only as good as your last tweet.
I fancy that, one day soon, the Oscars will have a specific category for "Best Social Media Performance of the Year."
Just imagine the gushing acceptance speech, as the winning star tries to read out the names of all their 38 million followers.
