This one-minute trailer for The Salvation of Billy Wayne Carter, a novella by M. David Hornbuckle, starts out with some interesting computer animation—the only jarring element is that while the man in the film is done up in a somewhat realistic style, the woman's facial features are much more cartoonish, and the effect is somewhat jarring. But a machinima book trailer is a great idea in principle—anybody else got one?
(Clarification: Although animator Peter Bernard goes by the handle "pbmachinima," this video's computer animation is actually built from scratch.)
