The Isle of Love is a 1922 recut of a 1920 American silent drama film Over the Rhine aka An Adventuress starring female impersonator Julian Eltinge.
The original film was titled Over the Rhine and was an anti German propaganda piece starring Julian Eltinge, a female impersonator, who was extremely popular at the time.
In 1922, after Valentino rose to fame with The Four Horsemen of the Apocalypse, and Virginia Rappe had died in what became a scandal, the film was released once again under the title The Isle of Love.
The Isle of Love featured a poorly spliced-together story, which mostly intended to cash in on Valentino's newfound fame despite his original role being quite small, and also on the fallout from Rappe's death.
The Isle of Love has yet to be released on DVD or home video, but a complete print of that version survives at the UCLA Film and Television Archive.
