MOUNTAINS, CITY, SEA
Why not film for three days, one day in each place on an iPod Nano. I don't think anyone has ever filmed a movie on an iPod Nano. I've heard of movies made on phones. Could have a narrative structure but with room for improvisation with four actors. I think it would be a really cool experiment. Could be Catskill, New York, Long Island, north of Boston or Maine.
Sequel, Camargue France
Maybe if there is a cinematographer out there interested, I could get the actor's side together.
