Fans of Dr. Seuss - one of the richest deceased celebrities - will be happy to know that a new animated film based on one of his beloved books is coming to the big screen.

'The Lorax' is about a young boy who lives in a world without trees. From the first trailer below, it looks like several things from the book have been changed to update the story. Didn't Hollywood learn from 'Horton Hears a Who'? Never mess with Seuss.

Still, it's a film with an environmental angle, colorful characters, hip music and top stars doing the voices. Basically, it's a license to print money.

'The Lorax,' which hits theaters in March of 2012, also stars Betty White, Danny DeVito, and Ed Helms.  (You have to admit that Devito as The Lorax is pretty good casting.) Check out the first trailer below.
