‘The Good, the Bad, the Weird’’ is an act of Asian-Italian fusion, an entertainment that arranges cinematic leftovers in eye-popping new ways. Kim Ji-woon, yet another bad boy of South Korean filmmaking, indulges his jones for all things Sergio Leone to create an Eastern western that, unlike Akira Kurosawa’s classic samurai movies, goes for shallow pop instead of narrative depth. It’s a lot of fun before it wears you out, and it wears you out sooner than it should.
That said, it’s a kick to watch actor Song Kang-ho repurpose Eli Wallach’s Tuco — a.k.a. “The Ugly’’ — from Leone’s 1966 “The Good, the Bad, and the Ugly’’ (a movie that itself owed a lot to Kurosawa). Song’s character, a high-spirited bandit named Yoon Tae-goo, has managed to get his grubby mitts on an ancient treasure map in 1930s occupied Manchuria, but he’s only a half-step ahead of other interested parties: the invading Japanese Army, a rival gang known as the Ghost Market Thugs, and icy killer Park Chang-yi (Lee Byung-hun), who’s working (at least temporarily) for a Korean Mr. Big and whom you can call “The Bad.’’ With his slicked-down bangs and lethal stare, Lee appears to have just stepped over from one of Korea’s many high-speed gangster movies.
