South Korean director Bong Joon-ho’s thriller “Mother” has nabbed the best film award at this year’s Asian Film Awards.

The movie also picked up the awards for best actress and best screenwriter at the fourth Asian Film Awards ceremony held at the Hong Kong Convention and Exhibition Center on Monday.

The award for best visual effects went to another South Korean movie --- “Thirst” directed by Park Chan-wook.

Launched in 2007, the Asian Film Awards are presented annually by the Hong Kong International Film Festival Society to recognize excellence in Asian cinema.

Last year, South Korean actor Jung Woo-sung won the award for best supporting actor for his role in the movie “The Good, the Bad, the Weird,” while the South Korean film “Chaser” grabbed the award for best editing.
