Given the billions of people there are roaming the Earth, the chances of being completely unique are pretty slim. It's not a huge surprise, then, when the occasional
comes along. Usually, these are just regular folk who happen to look like a big-name celeb, and who inevitably spend their lives dodging autographs and avoiding creepy "fans" who think they've just run into their icon in Walmart or something.
Sometimes, however,
, which complicates the matter somewhat. Whenever they're spotted in the street, they're not sure whether they've been recognized for their own talent, or for someone else's.
Here are 22 celebs who have doppelgangers in Hollywood - but can you tell who's who?
Both are famous for starring in fantasy films based on best-selling book franchises and both look like they've been 17 years old for the last ten years.
These two looked more similar to one another when they were younger, but Keira and Natalie still bear a strong resemblance to each other.
3. Dax Shepard/Zach Braff
If you saw both these guys walking along the street, you could be forgiven for thinking they were brothers.
From the right angle, these two look remarkably similar and Hale claims to have been approached by Gomez's fans before.
If you told me that Jamie Presley was just Margot Robbie from ten years into the future, I would totally believe it.

There's an obvious age difference here, but the pair could pass for father and son.
Depending on how clued-up you are on celebrity faces, a lot of these people could easily be mistaken for one another. Can you think of anyone else who should be added to the list?
