Revealing mistake: When Dae-su enters the room of one of his nemesis, his computer screen shows information about the stock exchange. The Internet address on the screen is: C:/DocumentsandSettings/[.]/OldBoy/[.], which would be a link to a folder on that computer, not an Internet address.

Oldboy (2003)
Plot summary
Directed by: Chan-wook Park
Starring: Hye-jeong Kang, Ji-tae Yu, Min-sik Choi, Dae-han Ji
A man is abruptly kidnapped and held prisoner for 15 years without any reason for his kidnap nor his release. He is given a phone, a wallet full of money and 5 days to work out who did this and more importantly why, and if he succeeds, the man behind the kidnapping will kill himself but if he fails, then the love of his life will die.
Woo-jin Lee: Dae-su Oh talks too much.
Trivia: Choi Min-sik had to eat four live octopuses for the infamous scene in which his character Oh Dae-su wants to "eat something alive." Min-sik is a Buddhist, and would pray before each take and profusely apologize to the octopuses before eating them. The director later personally thanked the octopuses during an acceptance speech for an award he got for the film.
Question: When Mido was trying to come up with a screen name for Oh Dae-Su early in the movie, why was Dae-Su so interested/startled by the mention of "The Count of Monte Cristo"?





Answer: Perhaps because in the movie/book "The Count of Monte Cristo" that's what happened to him. In the book/movie the hero Edmund Dantes is renamed "the Count" in order to disguise that fact that he is Dantes after having broken out of jail. This way he is free to seek revenge on the ones that put him in jail under false charges.
