David Giuntoli and Brandon Routh have been mistaken for each other before because of their similar facial features and both of them admitted as much during Comic Con earlier this month.
The lookalikes attended the event to promote their shows and managed to run into each other as well.
Thankfully, there was no awkwardness between David Giuntoli and Brandon Routh when they saw each other at Comic Con. They even managed to squeeze in photo together.
Even the "Grimm" star himself agreed their similar features. Then again, they do have a lot of differences as well.
"Me and Brandon Routh always get confused with one another, so we took a photo today to prove otherwise," he told Access Hollywood in an interview.
Giuntoli also clarified that the former "Superman" star is "a bit taller" than him, adding that he's a "nice fella."
"If we were like, a Russian nesting doll, I'd be the one inside of him," he further joked. "We're that similar."
The "Legends Of Tomorrow" star took the said photo himself and Giuntoli to Twitter and pointed out their differences as well. Based on the snap, he does, in fact, look taller than his doppelganger.
"People think @mistergiuntoli is me, & I am him! Proof we're not the same person! ...also... our hair-part is opposite," he hilariously told his followers, along with a selfie of the two of them together with their fingers linked.
Check out their adorable photo here and try to see what the other differences are between the two.
David Giuntoli and Brandon Routh aren't the only celebrities that could post as a stand-in for each other. Katy Perry and Zooey Deschanel's faces definitely resemble each other's. Pregnant ladies Naya Rivera and Kim Kardashian could pass off as real sisters as well.
How about "Game Of Thrones" star Kit Harington and Irish singer Hozier? Recently, Caitlyn Jenner's similarity to "American Horror Story" alum Jessica Lange also stirred up Hollywood.
