The Valencian publishing house Tirant lo Blanch, aimed at the university public, has a very interesting collection that mixes two seemingly distant concepts like cinema and law. The idea is apparently simple, but very effective in engaging readers looking for a more enjoyable way to approach issues that can be dry. The key is to find a legal expert willing to play along. Many have done so so far, and thus we find, for example, the criminal lawyer Jordi Nieva discussing democratic institutions based on John Ford's classic The Man Who Shot Liberty Valance. The latest addition to the publishing house is Joan Ridao, Professor of Constitutional Law at the UB and a lawyer in Parliament (and a former ERC leader), who tackles one of his specialities, the regulation of lobbies, based on the film Miss Sloane (2016), directed by John Madden and starring Jessica Chastain.
