Zeppelin is a 1971 British World War I action-drama directed by Étienne Périer. The film stars Michael York, Elke Sommer and Anton Diffring. Zeppelin depicts a fictitious German attempt to raid Great Britain in a giant Zeppelin to steal or destroy the Magna Carta from its hiding place in one of Scotland's castles.
During the First World War in 1915, Geoffrey Richter-Douglas (Michael York), a Scotsman of German descent, is a lieutenant in the British Army. He meets Stephanie (Alexandra Stewart), a German spy with whom he falls in love. She suggests that he escape to Germany, where the other members of his family and his friends are. As a loyal soldier, he reports this contact to his commanding officer, Captain Whitney, who also wants Geoffrey to go to Germany, but on a secret mission to steal the plans of the LZ36, a new type of Zeppelin under development at Friedrichshafen.
Geoffrey pretends to be a deserter and travels to Germany, even getting shot in the arm by fellow British agents to sell the Germans the ruse. At Friedrichshafen, he meets his long-time friend Professor Altschul (Marius Goring), who lives with his beautiful and much younger wife, Erika (Elke Sommer), both of whom are scientists working on the new airship. Erika suspects that Geoffrey may be up to something, but keeps her suspicions to herself.
Geoffrey quickly learns that German Intelligence did not bring him to Germany for a family reunion. Following a meeting with Intelligence Colonel Hirsch (Anton Diffring), he is assigned to the LZ36 on its maiden test flight. As soon as it is declared airworthy, to maintain absolute secrecy without first returning to base, the airship is to take part in a military operation to steal or destroy British historical documents, including the Magna Carta, from Balcoven Castle in Scotland. Geoffrey is to play a key role in the mission, to use his knowledge of the Scottish countryside to guide the airship very close to the castle at night while the craft is in glide mode, with its engines off. After leaving Germany, the zeppelin lands on a lake in Norway to refuel and take on board a specially trained squad of soldiers.
Geoffrey misdirects the craft's wireless operator just long enough to send a message about the LZ36's location to British intelligence. The wireless operator returns and, upon hearing the reply and realizing what Geoffrey had done, engages him in a fight. Geoffrey manages to knock him out, and throws him out an open window, telling the captain the wireless operator had fallen while scraping ice off the airship, as many craft personnel had been ordered to do. The explanation is believed, but Geoffrey does not have a chance to send any more information because Erika comes on the scene and removes an important radio component. The airship proceeds to Balcoven Castle.
Under cover of darkness Geoffrey navigates the airship on its final approach to the castle. A local farmer hears the sound of the airship's engines just before they are cut, and raises the alarm with the local military base, but he is not immediately believed. Geoffrey has no option but to participate in the assault, but manages to slip away to try to raise the alarm. He persuades a sceptical radio operator to contact London, but after being wounded by German soldiers, the dying operator mistakes Geoffrey for a German spy and shoots him in the arm. The German attack on the castle is initially successful, but the historical documents they are after are in vaults inaccessible to them.
Meanwhile, alerted by the farmer's report and the radio operator's chaotic call, the British Admiralty scrambles several aircraft squadrons and dispatches ground troops. The British troops engage the Germans in a firefight, who withdraw empty-handed rather than risk losing the Zeppelin. The airship manages to slip away in the dark with a much depleted crew, but shortly after first light is caught by pursuing British aircraft. Several aircraft are shot down in the ensuing dogfight, but the Zeppelin is badly damaged. Despite desperately lightening the airship in an effort to stay in the air, the survivors are forced to crash-land near the coast of the neutral Netherlands. Geoffrey, Erika and the few remaining crew members make their way ashore just as the Zeppelin explodes.
Written by producer Owen Crump, the story of Zeppelin is set in mid-1915, during the First World War. Although based on the Zeppelin raids over London and England, as a work of fiction, the film differs from reality in several aspects, especially involving a sub-plot involving espionage. Principal photography for the production began in late 1970.
J. Ronald Getty was an executive producer thought his GMF Picture Corp. The movie was to be the first of a three picture deal between GMF and Warner Bros.  Filming took place at Malta. Peter Carsten was injured shooting bayonet scenes in the film.
The airships seen in the film include a 37-and-18-foot (11.3 and 5.5 m) models based on the plans of the R33 class of British rigid airship, which was itself based on the German LZ76, captured intact in September 1916. A replica of the control car was constructed for closeups and interiors, copied from the intact control car of the R33 held at the Royal Air Force Museum London; other interiors were built from plans held by the museum.[N 1]
Exterior shots using the model were filmed over a large water tank in Malta; scenes showing the sheds in which the Zeppelin was housed were filmed at the historic R100/R101 airship sheds at Cardington, Bedfordshire, in England. Photographs taken from the air to depict the fictional Glen Mattock and Balcoven Castle were shot over Carreg Cennan Castle in Wales.
The air combat scenes were filmed using Lynn Garrison's collection of World War I replica aircraft, originally assembled for 20th Century Fox's The Blue Max (1966). During the aerial filming, one of the S.E.5a replicas flown by Irish Air Corps pilot Jim Liddy, collided with the Alouette helicopter used as a camera platform. Five people were killed, including Burch Williams, brother of Hollywood producer/director Elmo Williams.
Zeppelin was well received by the public, who viewed the Zeppelin airship as the real "star", but critical reaction was not positive. The review in Variety noted, "Zeppelin settles for being just another wartime melodrama, with some good aerial sequences and a powerful, brisk raid sequence in the finale." In his review, A. H. Weiler at The New York Times opined, "... the storied, giant, silver, cigar-shaped dirigible is carrying a flimsy, lighter-than-air spy tale that wouldn't burden a carrier pigeon."
