True Friendship
Young adult filmmakers all hope to show their works in international festivals like Sundance and Toronto. But what about really young filmmakers who aren't in film school yet and aren't， strictly speaking， even adults？
They are at the heart of Wingspan Arts Kids Film Festival， tomorrow， in a setting any director might envy： Lincoln Center. Complete with "red carpet" interviews and various awards， the festival has much in common with events for more experienced moviemakers， except for the age of the participants： about 8 to 18.
"What's really exciting is that it's film for kids by kids，" said Cori Gardner， managing director of Wingspan Arts， a
nonprofit organization offering youth programs in the New York area. This year the festival will include films not only from Wingspan but also from other city organizations and one from a middle school in Arlington， Virginia."We want to make this a national event."Ms. Gardner added.
The nine shorts to be shown range from a Claymation biography of B. B. King to a science fiction adventure set in the year 3005. "A lot of the material is really mature，" Ms. Gardner said， talking about films by the New York City branch of Global Action Project， a media arts and leadership-training group. "The Choice is about the history of a family and Master Anti-Smoker is about the angers of second-hand smoke."Dream of the Invisibles describes young immigrants'（移民）feelings of both belonging and not belonging in their adopted country.
The festival will end with an open reception at which other films will be shown. These include a music video and a full-length film whose title is Pressures.
