Flag in The Village - 2004 by M. Night Shyamalan

The Village 2004 made effective use of flags.  In particular a solid earthy yellow flag is flown along the border of the property.  It is considered a safe colour, that gives a little immunity form the others they must never speak of.  The Village is beautiful movie that captures the feels of suburban Pennsylvania.  Shyamalan is known for his slight of perception, his reveals allow people to enjoy his films on a second viewing, which seem like a different movie, since you are in the know and can see why characters behave the way the do. 

Here a young man looks as the border of the village.  Pondering the beings and colours that live on the other side, and why the bright colour red is forbidden.

A white community flag can be seen with our blind heroine.  She is standing just a little off the ways from the group.
