When we last saw Gye Doo-Shik in the 2001 Korean gangster comedy My Boss My Hero, he was a second-in-command gangster who was forced by his boss to get a high school diploma in order to move up the mob ladder. There, he was subjected to bullies, rival gangs, and various forms of corporal punishment. The film became a mega-hit and was etched forever into Korean pop culture history as a leading example of South Korea's popular gangster comedy genre. Five years later, Doo-Shik and company return for more of the same in the sequel My Boss, My Student. This time, there's more of everything -- a larger cast, more subplots, more violence, more gangsters, etc. Even the screen is wider. The result is a true blockbuster that brought twice the box office gross of its predecessor (as of now, it is the second highest-grossing Korean film of 2006).
