James D’Arcy (“Master and Commander,” “Cloud Atlas”), Jack Davenport (“Pirates of the Caribbean”) and Maria Valverde (“Exodus”) star in “Gernika,” a love story set against the infamous bombing of the Basque village, immortalized in Pablo Picasso’s “Guernica.” The fates of Henry – a cynical American correspondent who has lost his soul – and Teresa, one of the Republic’s censors and in charge of overseeing the news that journalists can send abroad, cross in Gernika.
