Thailand’s best directors take no prisoners in this aggressively scary ride, delivering four tales of horror guaranteed to shake, rattle and roll your nerves.

4BIA (a play on the word “phobia”) signals a departure from ghostly Thai films by presenting suspenseful, cautionary stories about violent retribution and aggressive karmic payback. In Happiness, a young woman begins to receive mysterious texts, while Tit for Tat is a shockingly bloody tale involving black magic and teens. The Middle chills the funny bone when a camping trip goes awry and Last Flight thrusts you onboard a flight from hell in which a flight attendant must travel with a mysterious cadaver. Directors Pisanthanakun, Purikitpanya and Wongpoom are no strangers to the horror genre, having previously delivered blood drenched flicks like Shutter and Alone and Body. The real surprise is romantic comedy director Thongkonthun (Iron Ladies), whose Happiness segment relishes in genuine creepy intelligence, ominous dread with very little dialogue and a horrific climax. Make no mistake, these directors relish in scaring their audience beyond loud sound effects and fans are taking note: the film has won several audience awards for its heart-pounding thrills and visual mayhem.
