Dreamworks Moon

Did anyone else notice this? Several times during the film, it appeared that the moon in the sky was directly lifted from the opening graphics for the Dreamworks logo. And at one point, there were 2 moons in the sky - one, a sliver of a moon, and the other, the Dreamworks moon. And my fiance swears that some of the backgrounds during the bull stampede scene were lifted from Lord Of the Rings and repainted.
