“After I made Oldboy, I realized that the only character who is not privy to the entire truth in that film was the female character; she was the only female character in the film, and she was excluded from the truth. That made me so uncomfortable in such a big way that is spurred me on to developing Lady Vengeance. That was the genesis from which I went on to make other films with strong female characters.”
