Writing for a film, writing for a book… there are more and more novelists writing scripts, and scriptwriters books. David Trueba is the author of film scripts like Los peores años de nuestra vida, Dance with the Devil, The Girl of your Dreams and Balseros; as a writer, his novels have been translated into more than fifteen languages, and he was awarded the 2008 Premio Nacional de la Crítica for his novel Learning to Lose. He talks to editor Malcolm Otero Barral about his experiences with both writing processes.
