Balshofer in 1918 as the anti-German war drama Over the Rhine, the project was reshaped and released in 1920 as An Adventuress—a cross-dressing caper set in the fictional republic of Alpania and headlined by female-impersonation star Julian Eltinge, with early appearances by Rudolph Valentino and Virginia Rappe. The film was later re-edited and reissued in 1922 as The Isle of Love.

Balshofer’s earlier feature—shot in 1918 as Over the Rhine and released in 1920 as An Adventuress—this version was issued to capitalize on Rudolph Valentino’s sudden stardom.
