Even though we are dealing with an animated movie, both directors spent four weeks filming in Havanna in 2007. In this way they collected a lot of material to provide their illustrators with information on movements and camera perspective. The vast number of interior and exterior Cuban spaces were inspired by a great treasure: a photographic archive brought to light a number of prints that practically documented every street corner of 1949 Havanna. The directors also uncovered a number of aerial photos from these times. The change of scenery to New York finally changes the film's atmoshere completely and shows the contrast to life in Havanna. Two worlds collide. The crew also tackled another challenge: to find a creative team of illustrators who were able to bring Mariscal's designs to live the way the director's imagined it. The outcome is “One of the Top 10 Films of the year!“ (BBC), one that will surely thrill any fan of jazz music – especially if he's a romantic. The film has been released on DVD recently!
