FILMING of the long-awaited third series of hit Netflix comedy Sex Education is currently underway, with crews spotted in Herefordshire.

The popular show on streaming service Netflix tells the story of sex therapist Dr Jean Milburn, played by Gillian Anderson and her son Otis, played by Asa Butterfield.

The pair live in a picturesque chalet overlooking a river near the fictional place of Moordale, but the house is actually in Symonds Yat, near Ross-on-Wye.

Fern White shared a brief video on Twitter of the Scandinavian-style chalet, which overlooks the river Wye.

Filming has also been underway in Llandogo, further south in the Wye Valley in Monmouthshire.

Keen-eyed locals have noticed a flurry of activity around Llandogo as cameras and sets have been put up.

One resident, Ray Philson, said that the actors arrived on scene around 3pm and had previously been filming in Tintern.

Season three had been delayed – it was originally due to be released this month – as there had been concerns over the filming due to the close contact nature of the show and the coronavirus pandemic.

It was meant to begin filming in April and May last year but didn't enter production until September and filming has just begun.

It is expected that we will see the finished product on Netflix either late this year or early in 2022.

A number of high-profile cast members have returned including Asa Butterfield who plays Otis, Gillian Anderson as Jean, Emma Mackey as Maeve and Ncuti Gatwa as Eric.

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

The clip 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.

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.
