As of March 2009, this is the highest grossing film to date in South Korea, selling a total of 13,019,740 tickets. This means that over 20% of the South Korean population watched the movie (although there were also some who went to see it several times).

The crew of the film used metal barrels to make the splash effects whenever the monster would dive into the water.

In the news montage that depicts public hysteria, the man following the shot of the Center for Disease Control is former Canadian deputy prime minister John Manley.

Park Nam-il: Look at that... Isn't that amazing? In this situation?

US Doctor in Morgue: Mr. Kim,

US Doctor trying to operate Gang-Du: [speaking to his colleague in private] The late Sgt. Donald, the first one classified as a victim of the virus, was given an extensive autopsy and no virus was found. He died of shock during the operation. Also, no traces of the virus were found in any of the patients quarantined. Simply put, so far, there is no virus whatsoever.
