From what I've read - the real Stealth Hawk does have a faceted fuselage, because it was developed around the time that the F117 was introduced into service - and as an earlier poster observed, computers at the time lacked the power to model continuously curved surfaces, such as found on the B2.
Actually knew a gentleman from the US who in a previous life worked as a civilian contractor maintaining military wokkas. One night after a few drinks, he claimed to have maintained said aircraft - and he quietly described them as "...looking quite like an F117."
BTW - the comments on that movie blog with the other photos give a true insight into the level of drop-kickery found amongst the average SPAM.
