i wouldn not call be back . a dinosaur story simply a kiddie version of jurassic park . i find it more interesting than that . like the former and it call into question the security of bring being from one era into ours . but it really open my eye when i see who provide the voice represent john goodman and rhea perlman and jay leno and walter cronkite and julia child and kenneth mar and yeardley smith and martin short and larry king . to paraphrase that represent a give actor and the cheer woman and the tonight show host and the most trusted name in news and a famous chef and the young frankenstein police chief and lisa simpson and one of the three amigo and the cnn guy . but i guess that i shouldn not focus only on the cast . i think that this movie have something for both child ( purely fun ) and adult ( natural history ) . true and it escapism and but the perceptive kind . i would actually say that john goodman do rex voice here be sort of a precursor to his voice work in monster inc. worth see .
