I think director Kim Jee-Woon is a fan and wanted to make his own interpretation of Fellini's LA DOLCE VITA with this movie. It is just because A BITTERSWEET LIFE and that movie almost have a similar title. The plot itself is indeed familiar. Especially, if you're a fan of gangster movie. A lot of my friends complained that this movie is a way too predictable. Well they were right. And its cinematography was amazing.
