With the support of the Great Neck Arts Center, a group of already successful young film makers are about to launch a new film, Pioneer 12, in Great Neck. Co-produced by Great Neck South High graduate Joseph Bakhash, the film is scheduled to be shot on the peninsula in mid-November. And you might be featured in the film!

Mr. Bakhash is looking for extras---children and adults---and he is looking for merchants to provide goods and services, as well as anyone with any special experience or expertise that could relate to film-making.

Residents will be needed for extras, and Mr. Bakhash is looking for a ''random selection of the general public.'' While the one to two days of shooting scenes with extras will probably be based in Great Neck, there might be location trips to the Hamptons or to New York City. While there is no pay, there certainly is the excitement of screen credit and actually being in a motion picture.

Local merchants are urged to participate and donate food services. Breakfast and lunch, in particular, will be needed for the cast and crew (about 25 people maximum) for the approximately six day shoot. A few dinners and snacks would also be much appreciated. And although the restaurants would not be paid, they would receive screen credit in a movie that will make the round of film festivals. ''We need each merchant to donate just one meal,'' said Mr. Bakhash.

Vehicular services will also be needed---both cars (or vans) and drivers---to drive people around and to deliver meals to the set.

And anyone with a production skill is invited to join the crew. If you know about lights, or technical equipment (including computers), or if you would like to set up scenes or work with costumes, you will be welcome. There are plenty of positions for interns and production assistants.

Pioneer 12 is a short film (25 minutes) about a mentally ill man released from a mental clinic and his attempts to integrate back into society. ''It's like a Twilight Zone movie, supernatural, extra-terrestrial, with interesting special effects,'' explained Great Neck Arts Center Executive Director Regina Gil.

The screenplay is by Aaron Feldman, a young writer and director whose short film An Incident Near Falaise was quite successful on the film festival circuit. Oritte Bendory, who produced Falaise with Mr. Bakhash, will also be producing Pioneer 12 with him.

Last spring Mr. Bakhash helped the Great Neck Arts Center initiate its Cinematheque Film Series, with Mr. Bakhash's film Nathan Grimm having its world premiere right here in Great Neck. Extremely impressed with the Arts Center's fantastic support, Mr. Bakhash has become a consultant for the Cinematheque series, and he returned to talk to Ms. Gil about support for his latest film.

''I asked Regina for help in getting a low-budget film off the ground,'' said Mr. Bakhash. Regina Gil offered immediate support, as she is most anxious to ''bring the film world back to Great Neck.''

Great Neck Plaza Mayor Bob Rosegarten was equally excited about filming in Great Neck, and he has been busy scouting the peninsula for interesting locations. ''The Great Neck community has a lot of everything, wonderful locations,'' said Mayor Rosegarten, ''and filming in Great Neck helps show everyone what a wonderful place we have.''

Noting that years ago many films were shot in Great Neck, Mayor Rosegarten said that the ''first thing'' he did when he became mayor was to establish a film commission for Great Neck Plaza. The commission, consisting of the mayor, Trustee Maryellen Gussack, and local marketing and public relations expert Robert Zimmerman, set out to try to get more films shot in the Plaza and on the Great Neck peninsula in general. And now he is ''extremely supportive'' of this new venture, filming Pioneer 12 right here in town.
