National Look Alike Day
National Look Alike Day on April 20 is a cheerful American observance dedicated to doppelgängers, celebrity impersonators, identical twins, and anyone who's ever been told 'you look just like so-and-so.' Created in 1980 by Jack Etzel as a tribute to his look-alike son, it's become an excuse for look-alike contests, genetic curiosity, and the occasional identity crisis.
Why it matters
SEEING DOUBLE
It’s National Look Alike Day. On April 20, America celebrates doppelgängers, celebrity impersonators, and the joy of looking just like someone else. Your twin is out there somewhere.
THE STORY
National Look Alike Day was established in 1980 by Jack Etzel, a grandfather from Pittsburgh, in honor of his son who closely resembled him. Etzel registered the day with Chase’s Calendar of Events (the unofficial registry of American observances). The date — April 20 — has no particular significance; Etzel picked it for convenience. The day grew from a personal tribute into a national observance celebrated by twin organizations, celebrity impersonators, and internet culture.
The science of look-alikes is fascinating. Identical twins share 100% of their DNA and are biologically the most look-alike humans possible. Fraternal twins share about 50%. Siblings, on average, also share 50%. Unrelated people — doppelgängers — can sometimes look strikingly alike due to similar genetic backgrounds, similar environments, or pure coincidence. A 2022 study published in Cell Reports found that strangers who looked alike shared surprisingly similar DNA profiles, suggesting doppelgängers are genetically closer than coincidence alone.
The celebrity-impersonator industry is a genuine American economy. Las Vegas alone hosts dozens of impersonator shows — Elvis Presley, Frank Sinatra, Marilyn Monroe, Cher, Elton John. Legends in Concert (Vegas) and Impersonator Productions employ professional impersonators. The world’s largest Elvis convention takes place in Graceland, Memphis, attracting 600+ Elvis impersonators from 20+ countries annually. Look-alike culture is business.
Social media has supercharged the look-alike tradition. Apps like ‘Gradient,’ ‘FaceApp,’ and various celebrity-match tools let users submit a selfie and get matched to a famous person. These tools have become a staple of Instagram, TikTok, and Twitter engagement. Historical look-alike moments — Adolfo Nicolás (ex-Jesuit superior general) and Ghandi; Charles Dickens and Matthew Gray Gubler (‘Criminal Minds’); Josef Stalin and Steve Buscemi — have become internet canon. The modern look-alike experience is entirely online.
In our society, to look like someone famous is almost to become them — briefly, and through no effort of your own.
FOUR FAMOUS HISTORICAL LOOK-ALIKES
Coincidental resemblances that captured imaginations:
Charles Dickens & Matthew Gray Gubler
The ‘Criminal Minds’ actor and the 19th-century novelist have a striking resemblance — widely circulated online. Not genetically related; just a cosmic coincidence.
Josef Stalin & Steve Buscemi
A famous internet meme. Young Stalin (seminary photo) looks remarkably like actor Steve Buscemi. Buscemi has acknowledged the resemblance humorously.
Nicolas Cage & John Travolta
Played face-swapped versions of each other in ‘Face/Off’ (1997). Their resemblance is deliberate film casting, but they genuinely do share facial features.
Elvis Presley Tribute Artists
The ultimate commercial doppelgänger industry. ‘Elvis tribute artists’ are a legitimate Vegas profession. Graceland’s International Elvis Convention draws hundreds.
LOOK-ALIKE CULTURE WORLDWIDE
How different countries celebrate human resemblance:
DID YOU KNOW?!
You share 99.9% of your DNA with every human.
All humans are 99.9% genetically identical. The 0.1% that varies accounts for all human appearance variation. Doppelgängers simply share more of the variable 0.1% by chance.
Fingerprints of identical twins differ.
Even identical twins — who share 100% of DNA — have different fingerprints. Fingerprint patterns form partly based on uterine positioning, not genes alone. Twin courts still use fingerprints for identification.
Facial recognition software can be fooled by look-alikes.
A 2018 study found that current facial-recognition AI gets about 10-20% false positives on close doppelgängers. This has legal implications for surveillance and criminal identification.
The most famous historical doppelgänger case: the Tichborne Claimant.
In 1866, a man claimed to be the missing English aristocrat Sir Roger Tichborne — despite clear physical differences. His look-alike resemblance was enough to fool many. The resulting trial was one of the longest in English history.
