John Connor rallying with troops
behind a tattered American Flag
A tattered US Flag waves defiantly in the beginning of Terminator 3 - Rise of the Machines 2003. Standing in front of the flag is John Connor, the key individual responsible for winning the war against the machines.
As it goes with time travel movies, in this alternate future Judgement Day still happens but by different means.
Notice two Confederate and POW MIA flag
The Confederate Flag and POW MIA flags also make an appearance in this movie when one of the Terminators seeks clothes at the bar. The flags hang along the wall and are folded. They are not flying in traditional flag pole fashion but rather as a decorative background for the walls.
Flag of Texas - hung upside down
The flag of Texas is in the background, along the wall, but it is hung upside down which is a common mistake.
A way to remember how to hang the flag of Texas - is to remember that Texas shed blood towards the south with Mexico to be independent, while North Carolina shed blood to the north with Canada for independence. The red bloody bar of Texas and North Carolina are in sync with the direction of spilling blood with 'normal' map positioning. Thus the red bar of Texas is on the bottom-south side towards Mexico while the red bar of North Carolina is on the top-north side towards Canada.
