Highest Grossing Pixar Films

I've just returned from a little party we threw for my brother's 30th birthday and, as usual, there were plenty of debates / arguments / intense discussions.

One topic was Pixar films.  We debated which was the best, which was the worst and which was the highest grossing Pixar movie of them all.  I just googled it and can confirm the order in terms of worldwide gross in American dollars.

1. Finding Nemo - $864,625,978
2. The Incredibles - $631,442,092
3. Ratatouille - $621,416,583
4. Monsters, Inc. - $525,366,597
5. Toy Story 2 - $485,015,179
6. Cars - $461,981,604
7. A Bug's Life - $363,398,565
8. Toy Story - $361,958,736
9. WALL-E - $169,162,412 and counting
