Luck-Key

When a ruthless Korean hitman gets injured and becomes an amnesiac, a suicidally depressed bit-part actor seizes the opportunity to appropriate his identity. A decently funny fish out of water comedy with the actor pretending to be an assassin, and the hitman assuming the life of the actor, becoming a big success before suddenly remembering his old life. Falters by relying on some fairly goofy romantic comedy tropes in the final third, but there's some adequate entertainment to be had here.

Wow, the film description fools you, it is one if the most heart warming films i have ever seen. Beautiful soundtrack and what a script to fit the brilliant plot. Only shame is what happened at the end, does a knife suddenly stop working
