How old the stars of 'Stranger Things' are compared to their characters on season 4

Actress Millie Bobby Brown is 18, while her character Eleven should be on the show for about 14 years.

When Eleven first introduced us at the show, we didn't know his exact age - but his mother had been trying to find him for about 12 years.

Now it's about two years later, which means that Eleven is about 14 years old.

They finished high school between seasons two and three and are now freshmen in high school in the fourth season of "Stranger Things".

Of all the actors and their fictional opponents, Schnapp once stood closest to his character.

Like the rest of the group of friends, Luke is in his freshman year of high school in the fourth season of "Stranger Things." 

McLaughlin was the first of his young costers to get a driver's license, and now he is almost out of his drinking age.
