The X Files and Game of Thrones: Exactly where you've seen the cast of Sex Education before.

Although it’s only been two weeks since Netflix released season two of Sex Educationit’s safe to say the comedy-drama series has been absolutely devoured by fans.

The second season of the sex-positive series, which was released in mid-January, explores all the awkward intimacies of sexuality, identity, and relationships.

Watch the trailer for the second season of Sex Education below. Post continues after video.

But while the Netflix series has been praised for their commitment to inclusivity and being representative of today’s society, there’s something else we’ve noticed about the cast of Sex Education.

Besides being super relatable characters, the cast of the comedy-drama series are also extremely recognisable.

In fact, we’re pretty sure we spent most of the season trying to figure out why everyone looked incredibly familiar. ¯\_(ツ)_/¯

From The X Files to Game of Thrones, here’s exactly where you’ve seen the cast of Sex Education before.

If you've watched Sex Education's leading character, Otis Milburn (played by 22-year-old Asa Butterfield), then you’ve no doubt wondered to yourself: "Where do I know him from?".

Butterfield also starred in the TV series Merlin, Nanny McPhee and the Big Bang, Miss Peregrine's Home for Peculiar Children and Journey's End.
