Why actors get mistaken for each other: eight causes

Most actor lookalikes come down to reasons performers may be mistaken for each other, and this page lists those reasons, not named pairs. A list of people cannot be checked, cannot be corrected, and does something to the people on it that they did not agree to.

It is a list of the reasons two performers get confused, which turns out to be more useful. Every entry on it is something you can look for the next time the feeling arrives.

What to take away

The list

1. The headshot. The professional headshot is a portrait genre with taught and inherited rules: plain background, even light, direct gaze, a specific crop, a mild controlled expression, retouching to a shared standard. Thousands of performers are photographed to the same recipe by a small number of specialists. Two headshots look alike partly because headshots look alike. What a production actually measures is a different set of things, and none of them is in the headshot.

2. Casting type. Casting works in categories. A breakdown asks for a build, an age range, a quality. Performers who fit the same category are sent to the same rooms, get the same kinds of parts and are seen by audiences in the same kinds of frames. The audience's sense that they resemble each other is partly the memory of them occupying the same slot.

3. The same role. Two performers who have played the same character, or the same kind of character, are compared in costume. The costume, the hair design and the lighting scheme of that kind of production were shared before either of them arrived. James Bond is the plainest case: Sean Connery, Roger Moore, Pierce Brosnan and Daniel Craig each played him, and the audience mostly saw each of them in the same dinner jacket, holding the same pose, in the series' own lighting.

4. Period grooming. A production set in a given decade puts every performer in that decade's hair and clothes. Two actors who both worked in period pieces from the same era have been seen by the public with the same haircuts, and hair frames the face more than any feature inside it does. A series set in the 1960s, such as "Mad Men", puts its whole cast in that decade's cuts and suits, and viewers carry those images into every later comparison.

5. The hair and makeup department. Within one production, the department applies one style to the whole cast, so that the film has a look. Across productions of the same genre, departments reach for the same references. The stack of styling that sits over a performer's face is a professional product, and professionals within a genre produce similar products.

6. Publicity photography. A performer's most circulated images come from a small number of press events and campaigns, shot by a small number of agencies, with the same lighting rigs and the same lens choices. Two performers photographed at the same kind of event, such as the Academy Awards red carpet or a Cannes Film Festival photocall, in the same kind of light, from the same kind of distance, have been through the same optical process.

7. Age at fame. Two performers who became known at a similar age are held in memory at that age. Confusion between them is usually confusion between two younger images that were current at the same time.

8. Adjacent careers. Performers who broke through in the same year, in the same genre, in productions that were marketed together, share a slot in the audience's memory of that period. Time does the rest: the memory compresses, and the slot holds one face.

Why the industry converges on itself

None of this is accidental: a production is a risk, and casting is a formal trade cuts risk by hiring what already worked.

If a look sold last year, this year's breakdown asks for it, and agents send performers who match it. Photographers shoot them in the style that made the last one look right. The look is reinforced from every side until several working actors carry it at once.

The audience sees outputs, not process. They notice several actors share one look and conclude the actors happen to resemble each other. The resemblance was hired.

Performers who make a living from likeness understand this better than anyone. Their work depends on the look being assembled, not owned by a face.

What is left when the list is subtracted

Take a confident impression that two actors look alike and subtract the eight items above. Remove the headshot format, the shared type, the shared role, the period hair, the department's house style, the press-event lighting, the age both were famous at and the period both were famous in.

What remains is sometimes a genuine similarity of feature. Often it is nothing, and the confidence was built entirely from the list. Either way you now know what the impression was made of, and the eye's habit of over-detecting a face has been given less to work with.

Using the list

Common questions

Is there any list of actor lookalikes on this site?

No. A list of causes can be checked and corrected. A list of people cannot, and it publishes a judgment about their appearance without them.

Does typecasting really make actors look alike?

It makes them appear alike in the images the public sees, which is what a resemblance impression is built from.

Why is the headshot so influential?

It is the most standardized photograph of a performer's career, and the one most likely to be the image you have in mind.
