Edipo rey
Park Chan-wook stated that he named the main character Oh Dae-su "to remind the viewer of Oedipus." In one of the film's iconic shots, Yoo Ji-tae, who played Woo-jin, strikes an extraordinary yoga pose. Park Chan-wook said he designed this pose to convey "the image of Apollo." It was Apollo's prophecy that revealed Oedipus' fate in Sophocles' "Oedipus the King". The link to Oedipus Rex is only a minor element in most English-language criticism of the movie, while Koreans have made it a central theme. Sung Hee Kim wrote "Family seen through Greek tragedy and Korean movie – Oedipus the King and Old Boy." Kim Kyungae offers a different analysis, with Dae-su and Woo-jin both representing Oedipus. Besides the theme of unknown incest revealed, Oedipus gouges his eyes out to avoid seeing a world that despises the truth, while Oh Dae-su cuts off his tongue to avoid revealing the truth to his world.
