A $250million spy thriller filmed in Basingstoke has launched on Prime Video.

Citadel, a six-part series about a global spy agency starring Richard Madden and Priyanka Chopra Jonas, was filmed in Basingstoke two years ago in March and August 2021.

At the time, the cast and crew of the big budget production descended on Basing View, when lorries, trailers, flood-lights and catering facilities packed into a council car park, with 24 hour security patrolling the site.

Members of the public visited the area to try and catch a glimpse of the famous cast, but security guards tried to dupe those turning up saying they were filming a mayonnaise advert to avoid disruption.

Bodyguard actor Richard Madden was spotted walking outside the set of the Grade II listed building Mountbatten House.

It is understood that the five-storey building was sold for £2m in 2019 to Squarestone Growth, and was reportedly converted into a hospital set for filming.

Filming re-commenced in August for the programme when the cast and crew returned to finish filming scenes, according to the owners of the neighbouring Hartley’s Kitchen.

The first two episodes of Citadel were shown on Prime Video on April 28 and it has been met with mixed reviews.

The series was commissioned before the pandemic but its pilot episode was rejected. The original director was replaced and the series was given a radical overhaul.

It has become one of the most expensive streamed series of all time, behind the $465m The Lord of the Rings: The Rings of Power.

Citadel tells the story of a global spy agency following elite agents Mason Kane (Madden) and Nadia Sinh (Chopra Jonas) whose memories are wiped when the agency collapsed eight years ago.

Unaware of their past lives as spies, they have been living new lives until Bernard Orlick (Stanley Tucci) tracks down Mason, who then seeks out Nadia.

But can they stop Citadel’s enemy, Manticore, before it is too late?

It will air on Fridays this spring and has reportedly become the number-one web show in the world.
