How smart is Vin Diesel in Babylon A.D. , the dystopian thriller about genetic engineering and religion and the evils of science? He might just be smart enough to outthink a smart missile. This clip which IGN posted is most notable for reminding everyone that Michelle Yeoh is actually in this movie along with Vin. Babylon A.D. , about Diesel's mercenary character teaming up with Yeoh's killer nun to transport a special girl (Melanie Thierry) across a post-apocalyptic wasteland, opens on Friday. [IGN ]
