Tip of the hat to Kubrick?

There seems to be one explicit reference in this movie to that other well-known "clockwork" movie, Stanley Kubrick's A Clockwork Orange. It occurs in the scene where Ana is happily setting up in her new Parisian digs: she's dressed tomboyishly in white (like Alex's white droog overalls), putting up a poster of her favorite singer, Maria Callas (like Alex's picture of Beethoven in his room), and finally flings herself backward onto her bed like Alex does in his scene, luxuriating in her favorite beautiful music.

This movie's like a girly version of A Clockwork Orange, only with singing instead of ultraviolence!
