PRODUCTION has begun on the third series of the hit Netflix show Sex Education, which has scenes set in Herefordshire.

A video shared on Twitter showed cast members, including Gillian Anderson and Asa Butterfield, preparing for a return to set, with Anderson joking she still had "lockdown hair".

The on-screen mother and son live in a chalet in the Wye Valley, overlooking Symonds Yat near Ross-on-Wye.

The clip on Twitter also showed Butterfield, who plays Otis Milburn, brandishing his hair clippers and mulling which board games to take with him to set, before eventually settling on all of them.

It also featured Butterfield putting on his face covering before waving goodbye to his cats, while Chris Jenks, who plays Steve Morley, was disturbed during a relaxing bath with a loud alarm.

He was then seen rushing around throwing all his possessions into his luggage.

Sterrett's Caravan Park, also in Symonds Yat, is named, but was not a filming location, in the Netflix series.

Monmouth and Tintern are also recognisable locations used throughout the past two series and likely to make an appearance in this newest iteration of the show.

Meanwhile Connor Swindells, who plays Adam Groff, recorded video of himself arriving for a costume fitting and trying on an Indiana Jones-style hat, while Jojo Macari, who plays Kyle, grabbed his skateboard and said: "I've got to get back to school, let's get to Moordale."

The video also featured one cast member in heavy prosthetics, and showed Anderson posing with a cushion stuffed up her blouse, laughing: "That's me pregnant as Jean."

At the end of series two, Anderson's character Dr Jean Milburn discovered she is expecting a baby.

Netflix announced the show had been renewed for a third series in February, after the second series launched in January.

The programme has been praised by viewers for its frank depiction of sex and teenage emotion.
