Film proposal In mid-September 1965,
S. Benjamin Fisz, a former Hurricane pilot, saw aircraft practising for the Battle of Britain day, over
Hyde Park, London. He saw how teenagers did not recognise the aircraft. In that same second, Fisz had a proposal for what became the film. Fisz raced to his office, and telephoned the film executive
Freddy Thomas. Fisz asked Thomas if he had liked the film
The Longest Day. Thomas said that
The Longest Day had made much money. Fisz asked Thomas that if a similar film could be made about the Battle of Britain, that showed each side. Thomas said 'It would depend upon what the script was like'. In March 1966,
The Rank Organisation announced it would make nine films with a total cost of £7.5 million, of which it would provide £4 million. Two films were financed by Rank completely, a
Norman Wisdom movie and a "doctor" comedy (
Doctor on Toast which became
Doctor in Trouble). The others were
The Quiller Memorandum,
Deadlier than the Male,
Maroc 7,
Red Hot Ferrari (never made),
The Fifth Coin (never made),
The Battle of Britain and
The Long Duel. In May 1966,
Harry Saltzman telephoned Fisz, and asked about meeting over dinner that night. Fisz told Saltzman that he could find £1.5m for the film, and that the film would cost around £3.5m. Saltzmann said that he could find the required money. Saltzman approached
Paramount, but that proposal never happened. By 1967, Fisz was receiving thousands of letters from around the world about the proposed film, with many containing money. The film's writers proposed to set up a fund.
Script By the end of August 1967, a copy of the script was sent to Galland, to be 'checked'. Galland claimed that the description of the bombing by the Germans of civilians in London was a 'malicious distortion of the truth'. Oberst Hans Brustellin and Major Franz Frodel also advised. Former WAAF
Squadron Officer Claire Legge, from
East Sussex, gave the female military viewpoint. Claire had been at
RAF Tangmere during the battle; her husband was Spitfire test pilot
Jeffrey Quill.
Aircraft in 2015, still sporting the livery worn during filming of
Battle of Britain. It was also used in the 2017 film
Dunkirk The film required a large number of period aircraft. In September 1965, producers
Harry Saltzman and
S. Benjamin Fisz contacted former
RAF Bomber Command Group Captain T.G. 'Hamish' Mahaddie to find the aircraft and arrange their use. Eventually 100 aircraft were employed, called the "35th largest air force in the world". With Mahaddie's help, the producers located 109 Spitfires in the UK, of which 27 were available although only 12 could be made flyable. Mahaddie negotiated use of six Hawker Hurricanes, of which three were flying. The film helped preserve these aircraft, including a rare Spitfire Mk II which had been a gate guardian at
RAF Colerne in Wiltshire. Lieutenant Maurice Hynett, RN, on leave from duties at
Royal Aircraft Establishment,
Farnborough, flew a number of Spitfire sequences in the film. A rare Hawker Hurricane XII had been restored by Canadian Bob Diemert, who flew the aircraft in the film. Eight non-flying Spitfires and two Hurricanes were set dressing, with one Hurricane able to taxi. A
North American B-25 Mitchell N6578D, flown by pilots John "Jeff" Hawke and Duane Egli, was the primary filming platform for the aerial sequences. It was fitted with camera positions in the aircraft's nose, tail and waist gun positions. An additional camera, on an articulating arm, was mounted in the aircraft's bomb bay and captured 360-degree shots from below the aircraft. The top gun turret was replaced with a clear dome for the aerial director, who would co-ordinate the other aircraft by radio.
N6578D was painted garishly for line-up references As Luftwaffe stand-ins the producers obtained 32
CASA 2.111 twin-engined bombers, a Spanish-built, Merlin-powered version of the German
Heinkel He 111H-16. They also located 27
Hispano Aviacion Ha 1112 M1L 'Buchon', a Spanish version of the German
Messerschmitt Bf 109 single-engine fighter. The Buchons were altered to better resemble Bf 109Es, with mock machine guns and cannon, redundant tailplane struts, and rounded wingtips removed, but nothing could be done about the Merlin-powered ''Buchon's'' nose profile not resembling that of the "inverted" Daimler-Benz DB-601-driven Bf 109E's. After the film, one HA-1112 was donated to the German
Luftwaffenmuseum der Bundeswehr, and converted to a
Messerschmitt Bf 109 G-2 variant, depicting the insignias of German
ace Gustav Rödel. Two Heinkels and the 17 flyable Messerschmitts (including one dual-controlled HA-1112-M4L two-seater, used for conversion training and as a camera ship), were flown from Spain to England to complete the shoot. The flying sequences were led by George Elliott DFC (born c. 1923). During the war, as a Spitfire pilot, Elliott was shot down in 1944 when strafing over Austria, and had taken three months to get back to England, through
Yugoslavia. He had not taken part in the Battle of Britain. Aerial filming took place from April to November 1968. The summer of 1968 was not good for filming. The
Board of Trade would not let any filming of aerial sequences, if filming was not by led a senior RAF officer, for the safety of other aircraft. Elliott described the aerial filming as 'dangerous'. There were ten pilots flying German aircraft, led by Commandante Don Pedro Santa Cruz. The German cast were unhappy with the conduct of the four Texan pilots flying German aircraft. The Texans had supplied many historic aircraft, so had been allowed to fly in the film. The Texans appeared as Luftwaffe colonels. The four Texans walked about the set in their Luftwaffe senior officer uniforms, often giving people the 'Heil Hitler' salute. One Texan, whilst in his Luftwaffe uniform, would sing Mexican love songs, with his guitar.
Locations lent an air of authenticity Filming in England was at
Duxford,
Debden,
North Weald and
Hawkinge, all operational stations in 1940; one surviving First World War "Belfast" hangar at Duxford was blown up for the
Eagle Day sequence. Some filming also took place at
Bovingdon, a former wartime bomber airfield. Some aerial shots were also taken over the former RAF Sywell (now
Sywell Aerodrome in
Northamptonshire). The title sequence scene, showing a review of German bombers on the ground by Fieldmarshal Milch, was filmed at
Tablada aerodrome in Spain. Stunt coordinator Wilson Connie Edwards retained a Mark IX Spitfire, six Buchons, and a P-51 Mustang in lieu of payment, which were stored in Texas until sold to collectors in 2014. The village of
Chilham in
Kent became the base of operations for the radio controllers in the film.
Denton, another Kent village, and its pub, The Jackdaw Inn, features in the film as the location where
Christopher Plummer and his on-screen wife argue about her relocating closer to his posting. The Jackdaw has a room devoted to an extensive collection of RAF Second World War memorabilia. Many of the scenes in the film were filmed in Spain. The scenes at RAF Fighter Command were filmed at its headquarters,
RAF Bentley Priory. Air Chief Marshal Hugh Dowding's original office, with its original furniture, was used. RAF Henlow, Bedfordshire including its original flight tower (that was constructed from Spitfire and Hurricane parts shipping pallets) was used for Squadron ground sequences.
Aircraft models Permission was granted to the producers to use the
Royal Air Force Museum's Junkers Ju 87 Stuka dive-bomber, one of only two that survive intact. The 1943 aircraft was repainted and slightly modified to resemble a 1940 model Ju 87. The engine was found to be in excellent condition and there was little difficulty in starting it, but returning the aircraft to airworthiness was ultimately too costly for the filmmakers. Instead, to duplicate the steep dive of Ju 87 attacks, large models were flown by radio control. during a British night raid.|alt=The corner of a building topped by a dome To recreate airfield scenes with the limited number of period aircraft available for the film, large-scale models were used. The first requirement was for set decoration replicas. Production of full-size wood and fibreglass Hurricanes, Spitfires and Bf 109s commenced in a sort of production line set up at
Pinewood Studios. A number of the replicas were fitted with motorcycle engines to enable them to taxi. Although most of these replicas were destroyed during filming, a small number were made available to museums in the UK. The other need was for models in aerial sequences, and art director and model maker John Siddall was asked by the producer to create and head a team specifically for this because of his contacts in the modelling community. A test flight was arranged at
Lasham Airfield in
Hampshire in the UK, and a model was flown down the runway close behind a large American estate car with a cameraman in the rear. This test worked, leading to many radio-controlled models being constructed in the band rehearsal room at Pinewood Studios. Over two years, 82 Spitfires, Hurricanes, Messerschmitts and He 111s were built. ==Historical accuracy==
