Both movies feature friendships in difficult circumstances, themes of trust and betrayal and the relationship between North and South.

Both movies have the same director and a similar dark atmosphere. The lead in The Chaser is chasing a killer while the lead in The Yellow Sea is being chased in the aftermath of a hit gone wrong. The buildup in The Yellow Sea is slower but both movies have the same tense undertone.

Same lead, full of action, great fight choreography and stunts.

An unexpected new relationship lead the main characters to rethink their values and life choices. A Bittersweet Life has more action scenes while Breathless is more raw.

Both very violent movies where the lead is trying to pursue their own way of justice. Save the Green Planet has some dark comedy elements.
