I guess you could say that Bong Joon-ho and Song Kang-ho led me to Park Chan-wook’s films. After seeing Bong Joon-ho’s Snowpiercer (2013), I looked up Song Kang-ho, who plays the security specialist. His performance led me to Bong Joon-ho’s The Host (2006), then Park Chan-wook’s I’m a Cyborg, But That’s OK (2006), and Stoker (2013). Of course, Park’s Oldboy (2003) was in there. Song Kang-ho stars in Sympathy for Mr. Vengeance.
Then I found out Oldboy is actually the second film in his Vengeance trilogy. Watched the first in the trilogy yesterday and immediately bumped Sympathy for Lady Vengeance to the top of my queue.
