Gillian Anderson reunited with her on-screen son Asa Butterfield on Sunday as filming got underway for season two of the comedy at The Chalet in Symonds Yat.
She recently revealed the show deliberately amalgamated elements of British and American cultures in the hope of appealing to both audiences.
Sex Education is 'definitely set in the UK', according to the star and the characters have British accents, but also play American football and wear clothes straight out of a US 1980s teen comedy.
Speaking to the Radio Times, Gillian said: 'There is a bit of both worlds, decidedly, in the series, and the aim and the hope is that Americans won't notice. For instance, the Brits may notice that they are throwing American footballs, whereas the Americans won't notice that that might be strange for people speaking with British accents.
'The rules are shifting all the time in terms of how an audience receives the shows that they're watching, what they're willing to accept and what realms and worlds they're willing to step into to suspend their disbelief.
'I think Netflix feels quite strongly that they've hit on something with this amalgamation.'
