cheers

Also :
Baz Luhrmann, with Leonardo DiCaprio- The Great Gatsby (filmed in 3D)

Please don't miss Dr. Seuss' The Lorax. It had the best 3D I've seen so far in Hollywood (not counting IMAX 3D).

Yeah the Dr. Seuss' The Lorax does look good. There are 2 trailers out for that show. But I try to make it to all the kids animated features. Almost all the kids animated features have really good 3D. There are some duds. I have found most kids animated 3D movies have similar 3D qualities to the Dr. Seuss' The Lorax trailers. And they look absolutely spectacular in 3D Blu-Ray in Full HD 3D. Its why alot of the 3D Blu-rays run close to $50 usd.

cheers
