Mothra vs. Godzilla.

I've always loved Mothra, especially the image of her blowing Godzilla to the ground with the beating of her wings, and the match-up is top notch in depicting creature effects and life-like movement for all the monsters. After sitting through both the Japanese and US versions (the latter has an extre scene even), I have to applaud the effects, but each of them does go on for a bit too long.
