you ve probably seen some amazing wildlife documentaries. the ones that capture animals in those unbelievable natural settings. seems they are unbelievable, because they may be faked. at least that s the claim from one documentary producer. john donvan reports. reporter: animals on the screen. we love them. beethoven in the movie of that name. lassie! reporter: lassie in the classic tv show. and then, of course, there is flipper. all of whom were, we knew, essentially actors. trained animal performers following a script. but animals on screen this way, in the wildlife documentary. and this is disney s 1958 white wilderness, what made it so dazzling, and what made later films like the imax blockbuster wolves so enchanting, or whales, was the sheer wonder of seeing animals wild, in a world with so much accidental beauty.
