Journey to the West. A sort of mythic comedy-horror-fantasy with spiritual overtones. Wriiten, Produced, and Directed by Stephen Chow, so he pretty much has to answer for it—and, truthfully, I would doubt it would get made any other way. Way too individual. Chow also did Shaolin Soccer and Kung Fu Hustle, so you know how he brings in fantay welements.
And the mass dance scenes that open the movie are astounding. Think simply of the rehearsals.
