In the middle of the 60s Nespolo started using curved lines in his paintings. While modern painting had until then had been dominated by straight lines and therefore by a rational, geometric approach, curved lines brought back a wider freedom in shapes and concepts. Nespolo used simple curves as the core of his creations and these were probably responsible for his turn towards cinema. As curved lines divide a flat surface into pieces with a jigsaw effect, so a movie sequence is a jigsaw of overlapping shots undistinguished by human eye. Each movie scene is in turn interrupted, broken and distorted in a dynamic jigsaw for which the viewer is free to give his own interpretation.
