Against All Flags is a 1952 American pirate film directed by George Sherman, with uncredited assist from Douglas Sirk.

It features Errol Flynn as Lt. Brian Hawke, Maureen O'Hara as Prudence "Spitfire" Stevens, and Anthony Quinn as Roc Brasiliano.

British naval officer Brian Hawke volunteers with two other seamen to infiltrate a pirate base on Madagascar.

Meanwhile, Hawke has caught the eye of Spitfire Stevens, the only woman among the Coast Captains, which arouses Brasiliano's jealousy.

Patma, the daughter of the Moghul Emperor, disguised by her chaperone as just another woman, is left aboard the burning vessel.

It is planned that a Royal Navy warship will sail into the harbour, with Hawke disabling the coastal cannons.

Hawke and his two accomplices are tied to a stake on the beach to be bitten by crabs and drowned, but Spitfire saves them.

Alexis Smith and Yvonne De Carlo were mentioned as possible female leads and Jack Gross was assigned to be the producer.

[10] By November, Howard Christie was set as producer, George Sherman as director and Maureen O'Hara the co-star.

It was Flynn's last Hollywood swashbuckler, as his next three (The Master of Ballantrae, The Dark Avenger, and the never-finished The Story of William Tell) were made in Europe.

O'Hara had to perform many of her close ups for love scenes opposite a black flag with an "x" on it while a script girl read his lines.

Because director George Sherman was working on Willie and Joe Back at the Front by then, the scenes were shot by Douglas Sirk.

"[23] The New York Times said Flynn "is a singular man among men and Maureen O'Hara... who is beautiful putty in his hands.

[25] Filmink magazine called it "a marvellous return to form" for Flynn, being "colourful, escapist entertainment, with a strong script and top-notch cast.

[2] Despite this Flynn did not work again for Universal for a number of years, leaving the US to live in Europe; he was reunited with the studio on Istanbul.
