Commitment: Boy Band Boy Is the Man

What's the most effective way for a K-pop singer to be taken seriously as a movie star? Follow the example set by Choi Seung-hyun, a.k.a. rapper T.O.P. from the Korean boy band Big Bang. Here, in director Park Hong-soo's espionage thriller Commitment, Choi has winningly taken on the role of Ri Myung-hoon, a North Korean assassin who's been so indoctrinated into the cause that he can barely register emotion on his face. From the outside at least, he's a killing machine. Bullied at high school? No reaction. Stabbed in the side? Not even a wince. Killing someone? Closed lips. At most, a glare. Admittedly, there's one scene in which Ri breaks down and cries -- his two sisters, one blood (Kim Yoo-jeong), one not (Han Ye-ri) -- have both been kidnapped, after all. But soon enough, this teen assassin is back to serving up stoic face. And you know what? It works.

Haven't we seen enough tongue-in-cheek James Bonds and Jason Bournes, enough smirking Bruce Willis anti-heroes and improbably cheerful Jackie Chan clowns. Choi's cold, merciless, unfeeling take on the spy abroad gives more by giving us so much less. It also makes the fights scenes -- of which there are many -- more intense. When the good guy doesn't have time to weak or make a wisecrack, you know that the martial arts action is taking his utmost attention. It's all about your level of commitment.

But then the South Koreans have always taken the North Koreans seriously, whether it's as estranged friends (J.S.A.: Joint Security Area) or respectable foes (The Berlin Files). Only the Americans have insisted that the North Koreans were bumbling idiots, most notably in the Seth Rogen/James Franco misfire of a frat boy comedy, The Interview. And we saw where that arrogance landed them. North Korea may be off the grid (and even off its rocker) but that doesn't mean they're incapable or incompetent or impotent. And now Hollywood knows that too. Might I recommend a few documentaries?

Hidden Floor: Welcome to Your New Home... Time to Meet the Dead Neighbors!

Hmm. Let's see. Daughter Joo-hee (Kim Yoo-jeong) has developed a rash and been caught stabbing her doll with a discarded syringe. Not good. Mother Min-young (Kim Seo-hyeong) is an overworked architect hallucinating her new apartment building as a shabby domicile ready for the wrecking ball. Not good either. What's going on here? It's Kwon Il-soon's Hidden Floor, a pretty good fright flick that's part of 4 Horror Tales, a quartet of low-budget scary movies circa 2006 -- all but one written by Yoo Il-han. Yoo definitely has a classic formula at work here: A horrible crime (in this case the murder of a stubborn tenant and her son) must be uncovered by the living if the latter wishes to escape becoming one of the bitter dead's casaulties. Not that anyone will be believe her! I mean, ghosts... Really? Who believes in such things! You must be joking!!! Equally laughable are many of the performances: Like most B-movies, the exaggerated performances in Hidden Floor underscore how flat the other ones are. The exception? Kim Yoo-jeong. As the troubled pre-schooler who creeps out her babysitter, Kim feels vulnerable and menacing at the same time. You know she knows something about that hidden floor but you don't know whether that's a help or a hindrance to her mom.

The Chaser: The Kid Stays in the Crime Picture

The reveal and the capture of the serial killer come so soon in The Chaser that you might think, there's no likelihood of unrelenting tension in the hours ahead. Well, you're wrong! Director Na Hong-in and fellow screenwriters Hong Won-chan and Lee Shinho have made something more suspenseful than a standard whodunit; the mystery here isn't who did it, it's whether he'll get away with it despite his confession. What "it" is in this case is the attempted murder of a call girl (Seo Yeong-hie) whose morally compromised pimp (Kim Yun-seok) is undergoing a seismic shift inside as he searches for the lair of her last customer, a psychopath (Ha Jung-woo) held in detention by the cops. It's a wonderfully messy story with subplots involving police brutality, embezzlement, sex trafficking, auto insurance, church finances, and even a mayor who's been hit in the face with human feces. But aside from one glitch near the end in which a delightfully tough lady dick (Park Hyo-ju) inexplicably lets the murderer get away, the twists and turns of The Chaser keep you on your toes. Factor in that this is Na's first feature and an amazing performance by Kim Yoo-jeong as the prostitue's kid, and this movie is a super-impressive addition to Korean noir.
