Dwayne "The Rock" Johnson is possibly the most charismatic celebrity on the planet, and he's not ruling out using that talent on the campaign trail.

At the Democratic National Convention in Philadelphia, people are holding up signs urging him to run. And while he's ruling out a presidential run for 2016 — he missed filing deadlines, anyway — he still might run for office in the future.

"[I'm] grateful how this idea has become very real to a lot of people,""The Brahma Bull" wrote on Instagram. "Years from now if I feel I can step up and become a strong, impactful and authentic leader for the people and our country - I will."

As Time's Raisa Brunernoted, the "Pain & Gain" actor hasn't been shy about potentially entering the political realm. When British GQ asked him about a future in politics, he said that he's thinking about it:

"I'll be honest, I haven't ruled politics out. I'm not being coy when I say that, but at the moment I am not sure. I can't deny that the thought of being governor, the thought of being president, is alluring. And beyond that, it would be an opportunity to make a real impact on people's lives on a global scale."

He added the hashtag #PresidentRock to the Instagram post of someone holding a sign suggesting him for president, and it racked up more than 600,000 likes.

He also keeps tweeting about the presidency:

Of course, he wouldn't be the first actor to run for office.

Ronald Reagan was president of the Screen Actors Guild before becoming governor of California and then president. Arnold Schwarzenegger was one of the biggest movie star of the 1980s and '90s before becoming California governor. And reality-TV star Donald Trump officially claimed the Republican nomination for president last week.

The 2020 race is going to be interesting.
