A romantic "swashbuckler" adventure film, based on a story and screenplay written by Allen March (maybe a symbol-name standing for Helen "Élan" Marx, since nothing else at all is known for Allen March and this is the only script he wrote as a screenwriter -if he ever existed- and the only alternative existing script for the PIRATES OF TRIPOLI is forged: see
https://subslikescript.com/movie/Pirates_of_Tripoli-48493).
The movie was produced by the American director and producer Sam Katzman (of Jewish-Russian descent) who also produced for Henreid the 3 movies THE SIREN OF BAGDAD, THE THIEF OF DAMASCUS and JEAN LAFITTE, LAST OF THE BUCCANEERS..
It was directed by the American writer, producer and director Felix Ellison Feist (this was the last film he directed for the wide screen before jumping on TV).
THE GREAT STAR of the film is PAUL HENREID (the double or doppelganger of the Algerian philosopher Albert Camus, whose relationship with the movies of Henreid is certainly revealed in CASABLANCA and JOAN OF PARIS but here, in the PIRATES OF TRIPOLI, it reaches its height and full meaning upon the Flag of the Plague).
