Film crews are at Letchworth’s outdoor pool today, shooting a TV advert set for launch next month.

The production company shooting at Letchworth Outdoor Pool, off Icknield Way, is Sonny London – whose clients have ranged from beer giants Guinness, Stella Artois and Heineken to charity Barnardo’s and car firm Volkswagen.

The Norton Common car park has been closed yesterday and today during the filming at the pool, which is run by Stevenage Leisure Ltd.

A spokeswoman for North Herts District Council told the Comet that apart from the identity of the company doing the filming, all details were confidential until the advert campaign’s launch in June.
