No Superman, but saw "Cars" last weekend.
Here's a scene that's a typical right/left winger conflict.
In the town of Radiator Springs live an army jeep and a VW bus.
The jeep lives in a quonset hut (like the barracks in Gomer Pyle) and the VW lives in a psycodelic painted dome house.
They are next door neighbors.
Every morning, the jeep raises the American flag to the tune of "reville".
Just as the bugle starts, the stirring sounds of Jimi Hendrix's "Star Spangled Banner" is heard coming from the VW's house.
The jeep yells, "Trun that noise off!!!" The VW replies, "It's classic, man!! Jimi Hendrix!!"
The Jeep, "Sarge":

Saw "Cars" myself last weekend. Loved it. Good message, good animation, well produced. Did you stay for the very last scene at the very end of the credits?
Shalom.
