Jeremy Allen White, Timothée Chalamet and Glen Powell. Celebrity lookalike contests may be going viral now but they’re actually a time-honored form of entertainment.

For the roughly 8 billion of us on planet Earth, there's a 0.11 percent chance that each person has a doppelgänger somewhere in the world. Over the last few weeks-with a firm belief in this sliver of a statistic-film fans put out an all-points bulletin for lookalikes of their favorite actors.

Glen Powell, Timothée Chalamet, and more recognize that playing along — online or otherwise — with the real-life fun is better than a million junket interviews.

For as long as celebrities have existed, so have lookalike contests. It used to be traditional for the winner to take home a keepsake trophy, but the stakes are being raised these days – by the celebrities themselves.
