Flora and Son cast, Joseph Gordon-Levitt, Eve Hewson , Jack Reynor, Orén Kinlan, and director/producer/writer John Carney came out for the world premiere of the musical-themed film on Sunday at the Sundance Film Festival at The Ray Theatre in Park City, Utah. We got to chat with them about the movie and the importance of music, and its relationship with the film. In the musical-themed film, Flora, a young mother living in Dublin, lost touch with aspiration long ago. She juggles a sustenance-necessitated childcare job and a fraught co-parenting arrangement with her unkind ex as she tries to raise her son, Max. Flora and Max's brash rapport is both hilarious and revealing of their struggle to understand each other -- she searches for autonomy and self-love, masquerading as selfishness as his longing for independence and self-expression manifests as delinquency. When the two connect over a twice-discarded used guitar, the uniting power of music brings them closer than what simple proximity can provide.
