It was a marketing gimmick of the first order to open Takeshi Kitano's "Kantoku Banzai!" and Hitoshi Matsumoto's "Dai Nipponjin" on the same weekend. This head-to-head duel between films by the two reigning kings of Japanese comedy can only boost the box office of both.

A preliminary verdict of sorts has already been rendered by the Cannes Film Festival, where "Kantoku Banzai!" was rejected for the competition and "Dai Nipponjin" was selected for the Directors Fortnight section. A three-minute short Kitano made for an omnibus film commemorating Cannes' 60th anniversary screened — but so did 34 shorts by other directors. It's a cute throwaway, about a grimy worker wandering into a rundown rural theater where Kitano is the projectionist — and screws up the screening of Kitano's own "Kids Return" in the usual ways.

Similarly self-referential is "Kantoku Banzai," a film that Kitano has described as part of the ongoing "creative destruction" of his career, beginning in 2005 with "Takeshis'." In that film he played two versions of himself — one "Beat," a famous TV comedian, the other, "Takeshi," a scuffling actor who idolizes Beat. The film's many shifts between dream and reality are head-spinningly hard to follow — and "Takeshis' " was a box-office disappointment.
