Now, it seems the Matt Damon animal look-a-like has been revealed on TikTok as the owner of a golden retriever said she cannot unsee the similarities between the two.
TikToker Abby Larson (@ab.larson) posted a video and explained how a stranger came up to her and pointed out her dog's resemblance to the Good Willing Hunting and Jason Bourne actor while out at the dog park.
Since posting about her pooches' likeness in looks to the 51-year-old Hollywood actor, Larson's video has received 1.8m views, along with 320,000 likes and a lot of comments from people who couldn't help but make some Matt Damon - dog-related puns such as "Mutt Damon," "good boy hunting" and "Jason Bone."
While many also agreed that there was a physical resemblance between the dog and the actor.
One person joked: "You showed us two pics of Matt. Can we see the dog please!"
"Or, does Matt Damon look like your dog?" another person asked.
Someone else added: "To be fair Matt has the personality of a golden retriever."
"I need more animal/people doppelgängers…" a fourth person replied.
Laron's viral video even appeared on local news station WGN News - though anchors Dan Ponce and Lauren Jiggetts didn't exactly get the internet's hype.
"What?" a confused Jiggetts said and laughed in response, while Ponce said: "Come on," before they all agreed that "it's just a regular golden retriever."
