In Oldboy, a man named Dae-su is kidnapped and held in a small room for 15 years without knowing why. When he’s suddenly released, he seeks revenge, only to discover shocking truths that turn his world upside down. The film is filled with mind-blowing twists and dark secrets.
One key moment is when Dae-su finds out that his enemy, Woo-jin, has orchestrated everything to get back at him for a past mistake. The reveal of this connection is one of the most unexpected parts of the movie. It makes us question the true cost of revenge and the pain it causes.
Some fan theories suggest that Dae-su might have been tricked into thinking he was released to seek revenge, but in reality, he never left the prison at all. What if everything he saw after his release was part of a twisted mental game? Could it be all in his head?
An alternate ending could imagine Dae-su forgiving Woo-jin, choosing peace over vengeance. A prequel could dive into Woo-jin’s backstory, exploring the events that led him to orchestrate such an elaborate and cruel revenge plot, adding even more depth to the mystery.
