Filibus: Il misterioso pirata del cielo (Filibus: The Mysterious Pirate of the Skies) is a 1915 silent film about a lady thief who operates out of an airship. The main character is Filibus, and her alter ego is the Baroness de Troixmonde. She flies around robbing banks and stealing jewelry. She is pursued by the famous detective Hardy, who is trying to find his identity. In an amazing scene of audacity, she tells him that he is Filibus. By the film's climax, he starts to believe it.
This series includes examples of:
- Cool Airship: Filibus's airship includes an elevator that can lower her to the ground without her enemies knowing.
- Classy Cat-Burglar: Filibus is a true lady, being the Baroness de Troixmonde. She is only seen going after high-class targets.
- Dub Name Change: The single surviving print of this film is a Dutch release version with translated titles. Filibus's opponent is Inspector Hardy in this print, but the Italian publicity materials call him Detective Kutt-Hendy, so there seems to have been a name change in translation.
- Engineered Heroics: Filibus has her Mooks kidnap Leonora so that she can show up as the Count de la Brive, save the day, and sneak with her new identity into Inspector Hardy's social circle.
- Faceless Goons: Filibus's airship is stocked with a handful of silent, deadpan, completely indistinguishable crewmen.
- Just Friends: When Leo Sandy declares his love for Leonora, she totally friend-zones him.
- Love Triangle: Leo is in love with Leonora, who is in love with the Count de la Brive. When the Count turns out to be Filibus, they decide the natural course of action is for Leo and Leonora to get engaged.
- MacGuffin: The diamond eyes of the Egyptian cat statue.
- Meaningful Name: The Baroness de Troixmonde does indeed live in "three worlds" (trois mondes in French): she has identities as a posh lady, a posh count, and Filibus.
- Rescue Romance: Romance blossoms after Filibus "saves" Leonora from the staged abduction. (It's left ambiguous whether this was a goal of the rescue or an unexpected side effect.)
- Sky Pirate: Filibus is a Classy Catburglar who operates out of a Cool Airship.
- Theme Naming: It's probably no coincidence that Leo and Leonora, the two points of the Love Triangle who end up together, have matching names.
