Type 23 Frigates in the story. The main unit began filming on 1 April. They were unable to use Leavesden Studios, which they had constructed from an abandoned Rolls-Royce factory for GoldenEye, as George Lucas was using it for Star Wars: Episode I – The Phantom Menace, so instead they constructed sound stages in another derelict industrial site nearby. They also used the 007 Stage at Pinewood Studios. The scene at the "U.S. Air Base in the South China Sea" where Bond hands over the GPS encoder was actually filmed in the area known as Blue Section at RAF Lakenheath. The sea landing used the vast tank built for Titanic in Rosarito, Baja California. The MH-53J in the film was from the US Air Force's 352d Special Operations Group at RAF Mildenhall. Some scenes were planned to be filmed on location in Ho Chi Minh City, and the production had been granted a visa. It would have been the first major film to be shot in Vietnam since the Vietnam War. However, the visa was later rescinded by Vietnamese Prime Minister Võ Văn Kiệt two months after planning had begun, forcing filming to move to Bangkok. Bond spokesman Gordon Arnell claimed the Vietnamese were unhappy with crew and equipment needed for pyrotechnics, with a Vietnamese official saying it was due to "many complicated reasons". Anthony Waye says he believed the decision was caused after Vietnam's Communist government had viewed the opening credits of GoldenEye, which featured "semi-naked ladies smashing up hammer-and-sickle emblems with sledgehammers, illustrating the fall of communism." Two locations from previous Bond films were used: Brosnan and Hatcher's love scene was filmed at Stoke Park, which had been featured in Goldfinger, and the bay where they search for Carver's stealth boat is Phang Nga Bay, previously used for The Man with the Golden Gun. The exterior of Elliot Carver's CMGN Hamburg HQ was filmed at the IBM Building in Bedfont Lakes, Feltham, whilst Harmsworth Quays Printers Ltd in Surrey Quays, Rotherhithe, doubled for the interior of the Hamburg print facility. Spottiswoode tried to innovate in the action scenes. Since the director felt that after the tank chase in GoldenEye he could not use a bigger vehicle, a scene with Bond and Wai Lin on a BMW motorcycle was created. Another innovation was the remote-controlled car, which had no visible driver – an effect achieved by adapting a BMW
