Korean film director Shin Sang Ok and his actress wife, Choi Bun Hui, have sought political asylum at the U.S. Embassy in Vienna, Japan's Kyodo news service reported. The embassy would not comment. Originally from South Korea, the two disappeared from Hong Kong in separate incidents in 1978, with Seoul officials charging that they were abducted by North Korean agents. They reappeared in Yugoslavia in 1984, saying they had defected to North Korea. Shin won international film awards while in South Korea, and Choi was a popular actress there.
