Shades of “Rain Man” and “Dumb & Dumber” loom over “Oh! Brothers,” a sibling character comedy that provides a good platform for two well-known thesps. But “Brothers” isn’t funny enough as a pure movie to translate offshore. Locally, pic was a big fall hit, topping 3 million admissions, its theme of unlikely reunion carrying a special resonance for Korean auds.
When his father dies, amoral private dick Oh Sang-woo (Lee Jeong-jae from “An Affair”) needs to find his stepmother (Lee Hyeon-suk) to get his hands on dad’s loot and pay off a debt he owes a vicious cop (Lee Mun-shik). To this end, he invokes the help of his younger half-brother, Oh Bong-gu (Lee Beom-su from “Wet Dreams”). Bong-gu, who looks thirtysomethng, is actually a 12-year-old suffering from progeria, a premature aging disease, and Sang-woo uses his seemingly retarded nature to pry money from clients of a loan-shark (Park Yeong-gyu). First hour is leisurely with frequent jokes about Bong-gu’s sexual appetites. Two main thesps bond well, and proceedings get funnier in the second half, but with no special emotional undertow. Tech credits are OK.
