They say that each person has seven lookalikes in the world, which roughly means that every single person has a double. While this theory leaves much to be desired, the following list contains 15 pictures of celebrities and their historical doppelgangers, all of which are pretty amazing!

On a related note, if you happen to be interested in look-alikes, make sure you check out photographer Francois Brunelle’s latest project, in which he has photographed unrelated look-alikes from across the world; an interesting project if there ever was one.

1 Michael Cera

The “Juno” actor bears a striking resemblance to the woman in this 1940 painting of Dona Carmen Arconda by Spanish painter Ignacio Zuloaga.

2 Keanu Reeves

Keanu Reeves looks like he’s stepped right out of this 1875 picture of French actor Paul Mounet – an absolute dead ringer for the actor, facial hair included.

3 Justin Timberlake

4 Conan O’Brien

5 Alec Baldwin

Joseph G. Kolans (photograph, 1964) was an Army veteran and member of the Detroit Sportsman Congress, along with being Alec Baldwin’s doppelgänger.
