Chinese-language comedy Bad Guys Always Die is becoming one of the most anticipated productions at the upcoming Busan International Film Festival.

The Sino-South Korean movie, co-produced by box-office favorites Feng Xiaogang and Kang Je-gyu, will be released during the festival. Tickets for the movie sold out a few minutes after being released online.

The Busan festival, one of Asia's largest movie events, will screen 304 movies from 75 countries from Oct 1-10.

The movie is about the adventures of a Chinese teacher in a Busan primary school who gets involved in a crime by accident. The film features Taiwan idol star Chen Bo-lin and South Korean veteran actress Son Ye-jin.

In addition to the South Korean star, the movie features the country's pop rock band, CNBLUE. The South Korean star and the band could account for the intense interest the movie is garnering in Busan. The band composes and sings the movie's theme song, Cinderella, which is also its first Chinese-language song.
