For Uhm Jung-hwa, returning as the brave former secret agent Mi-young in “Okay! Madam: Bon Voyage” is far more than just reprising a role.

It is a challenge to her enduring power as a veteran actor and a rare milestone for a female-led action franchise in Korean cinema.

The 56-year-old has long established herself as a top multi-entertainer.

While dominating the music scene with groundbreaking hit songs, she has expanded her footprint on screens with defining roles in “Marriage Is a Crazy Thing” (2002) and “Singles” (2003). She also proved her ticket power with the 2009 disaster blockbuster “Haeundae,” which garnered over 11 million viewers.
