It seems like our bizarre obsession with doppelgängers or lookalikes is in no danger of subsiding any time soon. It’s a spooky but rather satisfying thing to know that there could be someone out there who looks in the mirror and sees the same reflection as you do. Yes, it’s incredibly narcissistic, too.

In case you haven't discovered it yet, there’s even an app that allows you to find your fine-art duplicate. Needless to say, people absolutely love it.

It's highly improbable you'll ever find an exact replica of yourself (who isn't a family member), but that hasn't stopped people from trying. The same goes for those of us who enjoy spotting the odd celeb double here and there, whether it’s another celebrity or just an ordinary someone walking down the street with their shopping bags.

Our fascination with human replicas continues, as sci-fi shows like Altered Carbon prove there is something unsavoury yet weirdly tempting about having a literal copy of yourself, just in case, you know, something happens to the original.

However, now it’s time to have a glimpse at some of the craziest celebrity lookalikes you will ever feast your curious eyes on with the 15 Celebrities Who Look Exactly Like Twins.

15. Linda Cardellini and Janeane Garofalo

Linda Cardellini found stardom whilst appearing in the high school series about misfits, Freaks and Geeks. Despite the show’s outstanding reception, it was cancelled after just one season due to its unpopular TV time-slot.

Over time, the show gained huge love from teens and adults alike and marked a turning point for the quality of writing in television. Nowadays, Cardellini continues to work in movies and television, and was recently given significant roles in shows Men and Bloodline.

Cardellini’s lookalike, 90s star Janeane Garofalo, tends to avoid dramatic flicks because she prefers comedic scripts that allow her to play quirky multi-faceted characters.

Although Garofalo is roughly eleven years older than Cardellini, we can’t help but notice the striking resemblance between the two actresses, with their dark wavy hair and sharp cheek bones. They are both of Irish and Italian descent, so this might have something to do with it.

14. Jesse Plemons and Matt Damon

Matt Damon has been acting for many years now. After gaining stardom with his lead role in Good Will Hunting (which he also co-wrote with his close friend, Ben Affleck), Damon was selected to play a wide range of characters from the obsessive Tom Ripley in The Talented Mr Ripley, to the stranded astronaut Mark Watney in The Martian.

Despite Damon being almost two decades older than Plemons, the actors could easily be related and what’s more, their careers seem to be following a similar trajectory with both deviating from typical Hollywood roles.

Also, they’re both especially good at playing "the creepy guy" (just watch Black Mirror episode USS Callister and new Suburbicon if you don’t believe us).

Whilst Plemons has been appearing in movies since the early '00s, he didn’t get properly noticed until his performance in Netflix show Fargo.

13. Logan Marshall-Green and Tom Hardy

Tom Hardy Logan Marshall-Green

Logan Marshall-Green hasn’t been able to conquer Hollywood in the same way that Tom Hardy has, yet he is slowly but surely making a name for himself. After starting out in shows 24 and The OC, he appeared in horror flick The Invitation and was also cast in the yet to be released sci-fi thriller, Upgrade.

Contrastingly, Tom Hardy is at the peak of his career and is likely to win an Oscar very soon. In fact, it’s rather surprising he hasn’t done so already. The actor has a long list of accomplishments, which includes The Drop, Mad Max: Fury Road and The Revenant.

Additionally, he will be appearing as Eddie Brock in the new Marvel flick, Venom.

Although Logan Marshall Green looks less like the Mad Max actor without a beard, when he’s got one on the go, they are basically the same guy.

12. Katy Perry and sca Brown

After becoming an instant star with her song “I Kissed a Girl”, Katy Perry claimed her spot as one of the ruling queens in pop music when she continued to produce chart toppers like “Firework”, “Teenage Dream” and “California Gurls”.

Her actress twin, sca Brown (who is just one year older than Perry), is still trying to find her place in the movie industry and has itted, during an interview for Elle in 2015, that her appearance has been a cause for concern when attempting to get movie offers.

She also said that in order to pay the bills, she ended up becoming a Katy Perry lookalike performer, but that she still wants to fulfil her dreams of becoming an accomplished actress. Her best role to date is that of a mermaid in the short film, Fish!

11. Keira Knightley and Daisy Ridley

Daisy Ridley Keira Knightley

Keira Knightley and Daisy Ridley have more in common than just their looks and mannerisms (if it wasn’t for their eyes and eyebrows, they’d be indistinguishable). As well as being from England, both actresses also started their assent to stardom on the sets of different Star Wars movies.

When Knightley was still a relatively unknown actress, she was booked to play (somewhat ironically given the nature of this list) Queen Amidala’s doppelgänger in Star Wars: Episode 1 - The Phantom Menace.

While this wasn’t Knightley’s break-out role, it was her first time appearing in a major Hollywood movie. Similarly, Ridley’s first ever big-budget film appearance was in Star Wars: The Force Awakens.

Furthermore, like Ridley’s immediate success from playing Rey in SW, Knightley became famous over night with her role in another popular Disney franchise, Pirates of the Caribbean.

10. John Boyega and Denzel Washington

At first glance, these two won't strike you as doppelgängers, however, the more you look, the more they become one person, and it’s freaky.

The two have insanely similar acting facial expressions including that "locked jaw" thing that Denzel’s been doing since his early performances. What’s more, both actors grew up in big cities; while Boyega is a born and bred Londoner, Washington was raised in New York.

Boyega gained international fame at twenty three years old after hitting the big screens as Finn in Star Wars: The Force Awakens and the actor will not be slowing down any time soon; his current projects include Pacific Rim Uprising and Watership Down (for which he will be doing the voice-over for Bigwig).

In 2017, his sixty three year old double, Denzel Washington, was nominated for an Academy Award for his performance in Fences and has just completed filming the long-awaited sequel, Equalizer 2.

9. Christopher Abbott and Kit Harington

If you watched the dark Netflix show The Sinners and initially thought that Jessica Biel’s husband was none other than the Warden of the North himself, then we don’t blame you, not one bit. The two actors look eerily alike and even the way they act has the same moody quality about it.

Although Christopher Abbott isn’t as famous as Kit Harington (for obvious reasons), his effortless style of acting is starting to get him some well-deserved recognition. Harington, on the other hand, is mostly known for one role: Jon Snow in Game of Thrones.

So, once the series reaches its finale, it will be interesting to see whether he decides to expand his repertoire a little. Either way, he’ll always be Jon Snow to us.

8. Jennifer Lawrence and Bella Hadid

Bella Hadid Jennifer Lawrence

Okay, so with this blue-eyed pair, you might need to take a closer look, but we assure you that these women have a scary amount of similarities. Bella Hadid would not look amiss sporting a bow and arrow and Jennifer Lawrence wouldn’t look out of place walking down a fashion-show catwalk either.

While Jennifer Lawrence opted for a career in movies, Bella Hadid’s ion lies with modelling. Despite being in their twenties, Lawrence and Hadid are at the height of their careers with Lawrence being up there with the highest paid actresses in the world and Hadid being one of the most sought-after models of her generation.

Although Hadid has expressed some interest in pursuing acting in the future, she has yet to star in anything other than commercials.

7. Justin Bieber and Paul Wesley

Oh, Justin Bieber-- you either love him or hate him. The now not-so-young singer’s dreams came true when he was spotted on You Tube by a talent scout (he was signed to Usher’s record label not long after).

He rapidly went on to become the biggest teen pop star in the world and today it's almost impossible to a time when Bieber wasn’t dominating the charts.

Bieber's doppelgänger, Paul Wesley, is eleven years older, yet still manages to confuse people with his heavy brows and dark blonde hair which closely resemble the Canadian singer’s.

Other than that, the two celebs don’t have that much in common, unless you count the fact that they have an enviably large female fanbase. You’ve probably spotted Wesley playing the broody Stefan Salvatore on the popular young adult show, The Vampire Diaries.

6. Charlie Hunnam and Travis Fimmel

Charlie Hunnam as well as Travis Fimmel

In the late '90s, English actor Charlie Hunnam was selected to play a fifteen year old teen coming to with his homosexuality in the British show, Queer as Folk.

After moving to the US, Hunnam was given a minor role in the WB series Young Americans (which was a rather peculiar Dawson’s Creek spin-off concerning Pacey and Dawson’s childhood friend). However, nowadays, Hunnam is most famous for his protagonist role in the FX show, Sons of Anarchy.

His Australian lookalike, actor Travis Fimmel, sports the same facial hair in his own series, Vikings, as Hunnam does in Sons of Anarchy. When Vikings first hit the screens, many people confused Ragnar Lothbrok (Fimmel's character) for Hunnam -- before a quick Google search, that is.

One thing’s for sure, these two know how to work the long hair look.
