Metamorphosis follows on the heels of past Illustra offerings, including Privileged Planet, Unlocking the Mystery of Life, and Darwin's Dilemma. It's probably true that with these films taken altogether, Illustra producer and documentarian Lad Allen has made the most easily accessible, visually stunning case for intelligent design available. If you have one shot at opening the mind of an uninformed and dismissive friend or family member, the kind who feels threatened by challenges to Darwinism, then presenting him with a copy of a 600-page volume like Signature in the Cell, or even a slimmer alternative like Darwin's Black Box, would probably be less effective than choosing one of Mr. Allen's DVDs. Among those, Metamorphosis might well make the best initial selection, since the argument for intelligent design doesn't come in till the third and final act. When it comes, it's a soft sell, preceded by a gorgeous, non-threatening nature film that only hints at what's ahead in Act III. In Act I, the focus is on the mind-blowing magical routine by which the caterpillar enters into the chrysalis, dissolves into a buttery blob and swiftly reconstitutes itself into a completely different insect, a butterfly.
