Movies and TvShows featuring "devour" theme.

An short movie that is illustrated in black and white using rather simple animation. The story is told by a narrator with a lovely British voice that reminded me of Malcolm McDowell and he does all the voices of all the characters as well. The story is about an ageless old crocodile that is quite nasty--even for a croc! Because he's older and lazy, he mostly just sits around doing very little.

In an all-out alien invasion, massive extra-terrestrial bolides penetrate Earth's atmosphere, trapping three friends in a wide forest clearing. Is this a prelude to war, or is this the beginning of humanity's total annihilation?
