They say everyone has a doppelganger somewhere, but is that true?

Judging by François Brunelle's series, "I'm not a look-alike," the answer may just be yes.

Brunelle has spent 20 years seeking out strangers who look alike, transitioning from film to digital cameras in the process.

To date, he's photographed 250 pairs of look-alikes in 25 different cities for his project, both finding his subjects himself on the streets of Montréal, Canada, where he's based, or having doppelgangers reach out to him to be photographed.

In some cases, companies, brands, or even countries, help him with his project, such as when the Colombian government had him shoot a campaign with the slogan "Let's choose to see what we have in common."

His main takeaway? "People are mostly the same wherever you go. We're all different, but at the same time, we all have the same preoccupations. Do I feel well? Do I look good? Is my hair OK?" he said.

He always shoots pairs in the studio together, asking them to bring simple outfits. He usually asks them to get close and touch each other, thus making them look less like strangers.

He took his first look-alike photo in 2000, with two men that he knew, and continued to shoot people that he recruited himself. However, once word of his project spread, people around the world started submitting themselves as doppelgangers for him to shoot.

He says that being a look-alike does not necessarily mean looking identical — it's more about maybe getting confused for one another at the mall.

"Sometimes people come in and I think they look the same — I don't even know which one is which. But after an hour or two, I don't think they look the same, it's very strange," he told Insider.

Initially, he thought these strangers would meet each other in the studio for the first time and be in shock, but more often than not the subjects themselves don't really see the similarities.

While he says he'd prefer to look more like James Dean than Mr. Bean, the idea to get doppelgangers in a room together for a photo shoot took root.

François Brunelle says he's always had a knack for seeing similarities between strangers, but his interest was piqued when he saw himself on TV. Apparently, he looks a lot like Rowan Atkinson's Mr. Bean.
