George Peppard's casting was announced in April 1965. The job of directing was given to
John Guillermin, who had impressed Fox's studio head,
Darryl F Zanuck, with
Guns at Batasi and
Rapture, two lower budgeted films he made for Fox. The film was shot in Ireland, at
Bray, County Wicklow's
Ardmore Studios. The budget was originally $3 million. Fox spent $250,000 on building nine war planes. Peppard learned to fly for the film and later called working with Guillermin "the most exciting creative experience I've ever had." Director of photography
Douglas Slocombe was hospitalized for three weeks with an injured back.
Elmo Williams said Guillermin was "indifferent to people getting hurt as long as he got realistic action...a hard-working, overly critical man whom the crew disliked."
Stunt flying The majority of the aircraft used in the film were converted
Tiger Moths and
Stampe SV.4s. Two
Pfalz D.IIIs were produced (by two separate companies) for the film, along with three Fokker D.VIIs and two
Fokker Dr.I triplanes. Other German aircraft were represented by repainted
Tiger Moths and Stampes. Two SE 5 flying replicas were made by the
Miles Aircraft company at Shoreham-by-Sea in West Sussex, England. Other British aircraft were mocked-up trainers made into British
S.E.5s. The German
lozenge camouflage was not universal to all units at the time the story takes place (
Spring 1918), but, in the film, aircraft of all German units are shown in this scheme. The Fokker Dr.I triplanes were purpose-built replicas. The Tiger Moth silhouette was more appropriate to British aircraft of the period, such as the S.E.5a (one of which Stachel shoots down during his first mission) and presents a good general impression of actual contemporary aircraft. The depictions of aerial combat in the film are particularly realistic. The aircraft ground scenes were shot at
Weston Aerodrome near
Dublin (which should not be confused with
RAF Weston-on-the-Green, England). Pilots from the
Irish Air Corps helped recreate the live dog-fight scenes, supported by a number of civilians, including former Air Transport Auxiliary pilot
Joan Hughes, who flew one of the Pfalz replicas, Charles Boddington and
Derek Piggott. Piggott was the only pilot willing to fly beneath the spans of a bridge. Taking the role of both German pilots and with multiple takes from contrasting camera angles, he ended up flying 15 times under the wide span of the Carrickabrack Railway Viaduct in
Fermoy,
County Cork, Ireland, and 17 times under the narrower span. The two Fokker Dr.I triplane replicas had about of clearance on each side when passing through the narrower span. He was able to fly through the arch reliably by aligning two scaffolding poles, one in the river and one on the far bank. Just before the scenes of flying beneath the bridge, one of the Triplanes executes what could be considered a near-perfect
barrel roll as seen from aft of the two Dr.Is used for the scene. Off screen, actor George Peppard flew one of the Pfalz used in the movie. The director had placed a flock of sheep next to the bridge so that they would scatter as the aircraft approached to show that the stunt was real and not simulated with models. However, by later takes, the sheep had become accustomed to the aircraft, and had to be scared by the shepherd instead. In the printed take, the sheep continued to graze, creating a continuity error which can be seen in the finished film. The entire collection of aircraft, uniforms and supporting equipment was purchased from 20th Century Fox by ex-
Royal Canadian Air Force pilot
Lynn Garrison. He kept the collection together in Ireland under his company, Blue Max Aviation, Ltd. Over the following years they played a part in ''
You Can't Win 'Em All, Darling Lili, Zeppelin, Von Richthofen and Brown'', and various television commercials, including a classic
Ridley Scott production promoting Opel's limited edition "Blue Max." Both of the Pfalz replicas and one Fokker D.VII now belong to New Zealand film director
Peter Jackson's 1914–18 Trust, with the Viv Bellamy-designed Pfalz now being on display at the Omaka Aviation Heritage Centre in New Zealand. All three aircraft are kept in fully airworthy condition. Another of the Fokker D.VII's is on display at the Southern Museum of Flight in Birmingham, Alabama.
Locations The scenes where the Germans come into the French village were filmed on Calary Bog in
County Wicklow, Ireland. For many weeks, the building of the village attracted the locals to watch it coming up. Then it was bombed and made to look destroyed. It was a local tourist attraction for a long time after the film had wrapped. The Berlin scenes were shot in Dublin.
Christ Church Cathedral and
Leinster House, the seat of the
Oireachtas, the Irish national parliament, are easily recognisable in the background of many scenes and
Trinity College served as the army headquarters where von Klugermann's office is located. Many of the flying scenes were shot at Weston Aerodrome (EIWT) near Lucan, Ireland, about 10 miles west of Dublin hence the name confusion with Weston-on-the-Green. Today there is a restaurant named after the movie at the Aerodrome. The final scene where Stachel meets his fate was filmed at Baldonnel, the Irish Air Corps' main base. The hangars seen in the movie were built for the Royal Air Force in 1918. The Carrickabrack Viaduct in Fermoy, County Cork was used for the scenes where Stachel and Von Klugermann (
James Mason) flew several times under the railway bridge. The view from the 19th century railway bridge which spans the River Blackwater is spectacular and it was one of the reasons the producers of The Blue Max chose it as one of the locations for the film.
Historical accuracy In an article entitled "About
The Blue Max the author, Jack D. Hunter, wrote: On the day of our arrival at the Bray Studios, we were shown to canvas director’s chairs with our names on the back and treated to rushes of some key action sequences. And I was literally left speechless when I saw Fokker D-7s with inverted engines and 1916-style insignia, Dr-1s with radial engines and smoke canisters on their landing gear struts, machine-guns that looked like Space Cadet props spouting flame without benefit of ammo tracks, every pilot wearing an Uhlan uniform and Battle of Britain style goggles, Gypsy Moths pretending to be Albatros D-3s, a Stampe presented as an RE-8—the anachronisms and goofs compounded. When I asked Delang about it later, he merely shrugged, rolled his eyes, and sighed resignedly. When I challenged the art director on something so glaring as a D-7 with curve-sided crosses, he shrugged, too. "That kind of cross photographs better," he said. Ah, but how about those machine-guns with no ammo feed tracks? Another shrug. "No big deal. People just watch the muzzle flashes." So much for the definitive World War I aviation movie. ==Music==
