In 1911, two French officers, Capitaine Morhange and Lieutenant Saint-Avit, become lost in the Sahara desert and discover the legendary kingdom of Atlantis, ruled by its ageless queen Antinéa. They become the latest in a line of captives whom she has taken as lovers, and who are killed and embalmed in gold after she has tired of them. Morhange however, already grieving for a lost love and planning to take holy orders, is indifferent to Antinéa's advances and rejects her. Angered and humiliated, she exploits the jealousy of his friend Saint-Avit and incites him to kill Morhange. Appalled by what he has done, Saint-Avit is helped to escape by Antinéa's secretary Tanit-Zerga, and after nearly dying in the desert from thirst and exhaustion, he is found by a patrol of soldiers. Saint-Avit returns to Paris and tries to resume his life, but he is unable to forget Antinéa. Three years later he returns to the desert and sets out to find her kingdom again, accompanied by another officer to whom he has told his story.

Much of the narrative is contained within a long flashback as Saint-Avit recounts his first visit to Antinéa; other shorter flashbacks are used within this framework, creating a fairly complex narrative structure.^[4]

When Jacques Feyder obtained the rights to film Benoit's novel, he insisted that the film should be made on location in the Sahara, a strategy which no filmmaker had previously used for a project on this scale. His whole cast and crew were taken to Algeria, first to the Aurès Mountains and then Djidjelli on the coast, for 8 months of filming. Even the interiors were filmed in an improvised studio in a tent outside Algiers, with sets by the painter Manuel Orazi.

Feyder initially borrowed production money from his cousin who was a director of Banque Thalmann. By the time of the film's release in October 1921, the costs had escalated to an unprecedented figure of nearly 2 million francs, and its financial backers rapidly sold their rights to the distributor Louis Aubert. The film soon became a huge success however; it ran at a Paris cinema for over one year and was widely sold abroad. Aubert re-released the film in 1928 and it had a renewed success.^[5]

The celebrity of the source novel as well as the much-reported circumstances of the production ensured that the film received plenty of attention on its release. Despite the 3-hour running time, it proved popular with the public and put Jacques Feyder into the front rank of French filmmakers. The critical reception of the film was more mixed, with particular objections made against the central performance by Stacia Napierkowska; she had been a dancer and well-known film actress for many years, but Feyder now regretted engaging her to portray Antinéa, especially when he found that she had gained an inappropriate amount of weight.^[5] Louis Delluc said: "There is one great actor in this film, that is the sand".^[6]

L'Atlantide was one of the earliest feature films to depict the French colonial presence in North Africa, and led the way for a series of other films made during the 1920s which emphasised the romantic and exotic aspects of the colonial experience; later examples in this colonial tradition included Le Bled (1929), Le Grand Jeu (1934), and La Bandera (1935).

A DVD version of the film was released by Lobster Films/MK2 in 2004, based on a restored copy at the Nederlands Filmmuseum in Amsterdam. This reveals the very high quality of the film's photography, and it includes a detailed scheme of colour tinting throughout the print. Its running time is 30+ minutes (300 metres) shorter than the reported length of the original. It has a new musical soundtrack by Eric Le Guen.^[7]
