In the prologue, the four musketeers stand in a framing device, as a medieval stage booth, and D'Artagnan steps forward and speaks to the audience, then steps back and resumes his position with the other three, who remained motionless; after the mid-point intermission, the same situation is repeated, with D'Artagnan speaking again to the audience, finishing with the words, "once more, once more...", after which the film resumes with the title card "20 years later". These were the two Douglas Fairbanks' first scenes with spoken dialogue, in his last silent film.
In this film, the Four Musketeers - Athos, Porthos, Aramis, and D'Artagnan - all sleep together in one bed, with the French phrase 'Un Pour Tous, Tous Pour Un' (One For All, All For One) inscribed on the headboard.
This was the only film in which Douglas Fairbanks dies on screen. It was done in an effort to appropriately symbolize his departure from silent films.
