Elle Fanning goes British in the first trailer for Sally Potter’s 1960s coming of age drama “Ginger and Rosa” (formerly “Bomb”), joining newcomer Alice Englert in the tale of the two titular best friends growing up amidst a tumultuous time in history. The film premiered to mixed reviews in Telluride and will be seen by a much larger pool when it screens in Toronto starting this Sunday. The two girls giggle, hold hands and protest the Cold War together, but the inevitable fissures in their bond are already visible, with Englert’s more sexually adventurous Rosa sharing some slightly inappropriate eye contact with Aleesandra Nivola, who plays Alice’s dad.

The trailer does nothing but amp up our anticipation of this film even more, with an ethereal Sofia Coppola meets Andrea Arnold meets “Mad Men” tone, and glimpses of the strong supporting cast that includes Oliver Platt, Annette Bening and Christina Hendricks. “Ginger and Rosa” has no US distribution yet, but hopefully that will change over the next week or so.
