A camera crew that appeared in Bovingdon airfield has sparked rumours it was filming the new Harry Potter film.

About 50 giant cranes have appeared on the runway rumoured to be part of a stunt scene for the forthcoming Harry Potter film Deathly Hallows.

While nothing has been confirmed, speculation is that the cranes were used for continued filming on the Seven Potters scene, which began several weeks ago.

Flipping vehicles and crashes were just some of the action shots believed to have been filmed at the airfield. However workers at the site claim the preparations are for a British Gas advert.
