Also, did you guys notice the different in photography in the "Mexico/Colombia" segments versus those taking place in Hawaii?

The segments in Mexico and Colombia were filmed with a filter greatly muting color, thus making the surroundings seem drab. The Hawaii segments were filmed with the unusual enhanced color, making the landscape look eye-poppingly stunning.

This was probably done in order to cover up the fact that this was all filmed in Hawaii. I always laugh at the scenes depicted in cold states during the winter, where there's snow on the ground. If you look closely, you can see that you're actually seeing Hawaii with snow inserted via CGI. It's done pretty well, though.
