The Mother of All Trailers is like spending two and a half minutes inside a studio executive's wet dream, in which his subconscious mind delivers up a genre-crossing, absurdly star-studded cinematic product that no test audience, no matter how fickle, could possibly resist. Of course, the production costs would probably stretch into the ten figures, but that's a problem one can safely ignore while still in the throes of REM sleep, at least until a nocturnal climax following the trailer's final frame cruelly releases him into a waking nightmare of budget overruns.
