Further clues have emerged as to what is being filmed in Watford’s Cassiobury Park after TV crews pitched up there this week.

Vans and minibuses were pictured alongside tents on Tuesday, with signs warning people that filming was taking place in the park.

The council had confirmed filming was taking place “for an advert”, but added it could not disclose what for.

On Wednesday during filming the cameras were focused on two young women drinking tea and chatting at a table with dogs.

The scene was relatively quiet, and there were around 20 members of crew and secruity standing nearby, with members of the public not being allowed to get close. 

At one stage a crew member confirmed to the Observer that an advert was being filmed but also declined to reveal what for.

He added that they planned to film until the end of yesterday (Wednesday).

Cassiobury Park was previously used as filming location in 1997 for Star Wars: Episode I – The Phantom Menace, with Whippendell Wood providing the backdrop of a forest for a scene involving Liam Neeson.
