NY filmmaker Mark Nickelsburg’s next short film is a love story. It’s about being on your own in the city. It’s about being eighteen months old. After winning awards for his first short Expiration, Nickelsburg wanted to continue making films but was loathe to spend time away from his son–so he made him the star of his short. The film, Harry Grows Up, has been selected to premeire at next week’s New York International Short Film Festival.
