The film was supposed to be the first part of a project. But due to its relatively poor performance at the box office when it was first released, the producers decided not to finish the second part. The nameless character that appears in the last scene played by Tony Leung Chiu-wai is supposedly the main character in the second part.
Su Lizhen also appears in another Wong Kar-Wai's film In the Mood for Love (2000). Both Su Lizhens are played by Maggie Cheung, although it has never been clearly indicated that both Lizhens are the same character.
This is the first part of Wong Kar Wai's trilogy, the 2nd is In the Mood for Love (2000) and the last one is 2046 (2004).
This gets its name from the title given to Rebel Without a Cause (1955) when it was released in China.
Marks the first collaboration between Wong and cinematographer Christopher Doyle, with whom he has since made six more films.
