According to Wong Kar-Wai, "Chungking Express" (1994) and "Fallen Angels" (1995) should be considered as a single film which is 3 hours long and watched as a double bill. When he was asked, why he had made these two stories which have no relationship at all to each other and how he could connect them, he replied,
"The main characters of 'Chungking Express' are not Fay Wang or Takashi Kaneshiro, but the city itself, the night and day of Hong Kong. 'Chungking Express' and 'Fallen Angels' together are the bright and dark of Hong Kong.”
He further added,
"I see the films as inter-reversible, the character of Fay Wang could be the character of Takashi in 'Fallen Angels'; Brigitte Lin in Chungking could be Leon Lai in 'Fallen Angels'. All of their characters are inter-reversible. Also, in Chungking we were shooting from a very long distance with long lenses, but the characters seem close to us."
P.S: On this day, 31 years ago, "Fallen Angels" (1995) was released in Hong Kong.
