Ma Dong-seok: Action Movies That Are a Genre in Themselves

Ma Dong-seok’s tough-guy screen persona springs from a background in boxing and fitness; before acting he worked as a personal trainer for MMA star Mark Coleman. Many of his roles feel tailored to that presence, pairing no-nonsense physicality with a strong moral code and an unexpected gift for comedy.

The combination of muscle, humor, and conviction has made him one of South Korea’s most bankable stars and helped turn several of his films into events. He anchors The Roundup franchise, which began with The Outlaws, as a fearsome police officer in Seoul’s Crime Unit; the series blends gritty action, sharp writing and comic beats, set box-office records, and continued with The Roundup: No Way Out and The Roundup: Punishment.

In The Gangster, The Cop, The Devil he plays mafia boss Jang Dong-soo, a role that leans into darker, Machiavellian traits as he teams with a cop to hunt a serial killer. His range shows across other highlights.
