"In South Korea, there is a train called the cinema train. It’s not the whole train, but one section, they show the movie inside the train from Seoul to Paju. The funny thing is, I was in the cinema train and I saw the movie “The Perks of Being a Wallflower.” And in the beginning of the movie, there’s a subtitle [that said] “This movie has been re-edited for the train’s duration.” So, for the length of the train ride, they cut it down. They should have just found a shorter movie. I was really pissed off. [laughs]” - Bong Joon-Ho.
