The two-disc Collector's Edition speaks directly to the film's core audience: kids and animation enthusiasts. Along with a widescreen version of the film, the first disc is very kid-friendly with two games ("Aladar's Adventure" is quite fun) and an informative short naming the dinosaurs seen in the movie. Using the "Fossil Dig" mode to watch the film, a viewer can see behind-the-scenes footage during certain scenes, as a dinosaur icon appears in the corner of the screen, and then is taken back to the film automatically. This is a great way to see the movie anew during repeated showings. As with previous Disney DVDs, there is plenty on the animation process on the second disc--hundreds of sketches, examples of the complex layering of scenes, and illustrations of the different forms of filmmaking from storyboards to 3-D workbooks. Six dropped sequences are shown (in various stages of completion) that hint at a darker-toned film. Best are the segments of how the show-stopping scenes (the asteroid impact, the "dino" cam) were created and some early presentation reels. The two commentary tracks are standard fare, but the hidden "Easter Eggs" (hidden features--look for the dinosaur-head skeleton) are quite fun, delving into other dinosaur tidbits from the Disney archives.
