All Around The World !

Looking at animated fims today, I don't feel like there's enough diversity. You hardly ever see other countries, other cultures, and other races.

(This is of no offense to anyone)
Most lead characters are american, caucasian, and rarely deal with some of the issues of today. I can remember those few that push outside the american culture.
For example, Disney's "Mulan" worked its way into China and not only delt with their way of life, but also with war. Let's not forget "Pochahontas", who introduced Indian life.
How about other races? Spanish, Italian, African American. By the way, you pretty much never see a lead character who is one of those races.

Other studios may share some diversity, but I'm more familiar with Disney.

It would also bo nice to have a little more reality behind the characters. Most of them appear perfect. I'm guessing you won't see too many overweight or unattractive characters leading.

There is, however, the character of Quese Motto in "The Huncheback of Notre dame" and the orgre considered ugly in "Shrek". It's mainly seen in tv movies.
What about disabilities? Do studios consider it unattractive to viewers or just too dull? Those factors can hit close to home. Would putting such facts into a film be a little too much for kids?
Audience members range from young and old. I'd love to travel when I finish college and learn about different cultures and have fun.

Some productions do respond to culture and put a little twist to it, like "Lilo and Stitch", where we learned about Hawaiian life and genetic experiments.

Thanks.
Note: I'm not always aware of upcoming animated films that touch this subject. I'd just like to know your opinions. Sorry if this has been discussed.
