Trivia: A Better Tomorrow
- Mark Gor's theme, which plays near the end of the restaurant shootout, is "Birdy's Flight" from the Nicolas Cage Vietnam movie Birdy.
- The English title "A Better Tomorrow" is the translated title of the song sung by the two school kids (in Mandarin) in the middle of the movie. It's a New Year's Eve song, usually sung by large groups.
- Mark Gor is based on a character (the "wandering knight") from a previous John Woo kung fu movie, Last Hurrah For Chivalry.
- Even though he is now universally known as an action hero, one of the main reasons John Woo wanted to cast Chow Yun-fat was because he didn't look like one.
