The Signal is a 2007 Argentine-Spanish neo-noir mystery drama film written by Eduardo Mignogna. Mignogna was going to direct the film as well. However, due to his death one year before the start of production, his friend and frequent collaborator, Ricardo Darín, took up the task. He was aided by Martín Hodara, who had his directorial debut. Darín also starred in the lead role, along with Diego Peretti, Julieta Díaz and Andrea Pietra.
