Blackbirds at Bangpleng, Kāh̄eẁā thī̀ bāng phelng - Check Out Some Songs is a 1994 Thai science fiction horror film. Though it is based on a novel by the famous Thai writer and politician Kukrit Pramoj, the story closely mirrors the 1957 novel The Midwich Cuckoos by John Wyndham, which itself was adapted into the 1960 film, Village of the Damned.
