For young Puerto Rican actor Marcel Ruiz, Summer of Three marks a turning point. Not only does he star in this film—shot and produced on the island—but for the first time he also takes on the roles of screenwriter and producer, participating in the entire creative process from start to finish. Adding to this is a deeply personal element: it is the first time he has worked under the direction of his father, Carlitos Ruiz-Ruiz.
