A Jewish refugee from Russia (Christina Ricci) is raised by an English family and finds work with a Paris opera company in the late 1930s; though relegated to anonymity (and a masculine role), she finds her mirror in a Romany horseman (Johnny Depp) who also performs. The other principal characters are mainly devices, and their opportunism fills several scenes with relatively traditional drama. But Ricci and Depp are worthy vessels for writer-director Sally Potter (Yes), whose narrative-rupturing use of music, dance, and other emotional expressions drives the movie much further than the plot. Everything revolves around the face of Ricci, whose quiet radiance gleams from the wry tangle of historical and satiric tropes and gentle gender allegory. With Cate Blanchett and John Turturro. R, 102 min.
