Acclaimed Polish filmmaker Marcel Lozinski takes his six-year-old son, Tomek, to the park on a mild spring day, and together they make a film of rare insight and meditative contemplation. Little Tomek is fitted with a small, hidden microphone, and the camera follows from a distance as he rides around the park on his scooter, observing nature around him (to the suggestive sounds of waltz) and then stopping and talking with people, mostly senior citizens, whom he meets by chance. Tomek’s high spirits and natural child’s curiosity about the world around him sparks conversations with the older generation, who share their wisdom and reflections on life with the young boy, who in turn shares his innocent philosophizing. As in his other films, such as Oscar-nominated “89 mm from Europe” (1993) and “I Remember” (2001), Lozinski takes a poetic and essayistic look at his subject. The result here is a delightful journey of discovery that touches lightly, but with great depth, on what it means to be alive.
