Thompson has been quietly (okay, not that quietly) rebuilding one of the most unpredictable careers in Hollywood, and the internet just noticed in a big way.
The former child star, who stole scenes in "Role Models" and "Cloudy with a Chance of Meatballs," has been popping up in fan videos, podcast clips, and viral posts that have people asking the same question: where has he been, and why does he look so happy?
For those who grew up in the 2000s, Thompson was everywhere.
He delivered the "you're welcome" line heard around the world, held his own opposite Paul Rudd, and became a Disney Channel staple.
Then, like a lot of kid actors, he stepped back from the spotlight, and the industry moved on without much of a goodbye.
What's different this time is the energy.
Recent clips show Thompson cracking jokes, reflecting on his early fame, and talking openly about the awkward middle years when casting directors stopped calling.
It's the kind of honesty that rarely makes it into celebrity interviews, and fans are eating it up.
TikTok and YouTube are full of reaction videos to his old scenes, with younger viewers discovering "Role Models" for the first time.
That kind of organic resurgence is gold in an era where studios are desperate for recognizable faces with built-in audiences.
Thompson has hinted at new projects, though he's been careful not to overpromise.
He's also leaned into comedy bits and personal storytelling, which suggests he's less interested in chasing the old version of fame and more focused on building something that actually fits.
The bigger story here is about second acts.
Hollywood loves a comeback narrative, but it rarely gives child stars the space to grow up on their own terms.
Thompson seems to be doing exactly that, and the reception has been warmer than anyone probably expected.
If the momentum holds, this could be the rare case where a viral moment turns into a real career chapter.
Either way, it's hard not to root for the guy who once told Paul Rudd he was welcome.
Nostalgia sells, but authenticity sells harder.
Thompson isn't pretending to be the kid from 2008, and that honesty might be the smartest move he's made in years.
Final Thoughts
Here's hoping Hollywood actually pays attention this time.
