French pop star-turned-actor Soko, not herself a dancer, got weeks of intensive coaching from American choreographer Jody Sperling, a specialist in the work of Fuller, nee Mary Louise Fuller of Illinois. Soko is onscreen constantly throughout the film, witnessing the violent death of her father on a western ranch, suffering the oppression of her strait-laced mother in Brooklyn, scheming the technology (and stealing the cash) required to realize her brilliant, angelic visions at the Folies Bergere. She finally gets her wish -- a gig at the Paris Opera -- only to fall apart physically at a crucial moment.
Most of the Paris theater scenes are shot in Prague, and most of the biographical stuff is fiction. Fuller was gay, and the film plays up the strong feelings her assistant (Melanie Thierry) has for her. But it takes a working relationship she had with the ample brunette dance revolutionary Isadora Duncan, who did study with Fuller, and turns it into a crush on a nubile blonde played by the too-young Lily-Rose Depp, who here feigns affection for the heroine to finagle a better contract. This and other evasions of fact render the project suspect, but the chance to observe Fuller's genius realized onstage almost redeems it.
