Other locations used included the real-life new town of Hemel Hempstead, Hertfordshire, which was under construction at the time and doubled for the fictional new town of Winnerden Flats. Other scenes were shot in London including Trafalgar Square, where the police agreed to hold up the traffic for just two minutes to allow Guest to take shots of trucks ferrying equipment through London to Winnerden Flats, and in the foyer of the House of Lords for the scene where Quatermass first meets Vincent Broadhead. The climactic scenes of the hurricane caused by the explosion of the Winnerden Flats complex were shot on the South Downs near Brighton. A minor mishap occurred during the filming of this scene when the wind machines blew Brian Donlevy's toupée off his head and the crew had to chase after it. As well as shooting on location, Guest and his crew made use of Stages 2 and 5 of the New Elstree Studios, the first Hammer production to shoot there. This was production designer Bernard Robinson's first film for Hammer; he went on to become their regular set designer, working on many Hammer films.
