JOHN CARNEY CAN’T help but make films about songwriting. The director of Once and Sing Street returns to the notepad with Flora And Son, a Dublin-set musical-romance about a single mum (Eve Hewson), who, through the power of Zoom, falls in love with music via her Los Angeles-based guitar teacher Jeff (Joseph Gordon-Levitt). Speaking with Empire, Carney dives deep into some of the songs he wrote for the story.
