Director Hong Sang-soo is making a new film with actress Kim Min-hee. It will be Hong's 22nd feature and the fifth starring Kim.
Shooting began in early September, film industry sources said Thursday.
Hong has worked with Kim since 2015 with "Right Now, Wrong Then", "On the Beach at Night Alone", "The Day After - 2017" and "Claire's Camera", which has not yet been released.
Their May-to-September romance went public last year, and they admitted to their extramarital relationship at a press event for "On the Beach at Night Alone" in March this year.
