A quote from the film (as spoken by Gainsbourg) is featured in the introduction to the 2001 Madonna song "What It Feels Like for a Girl".
Charlotte Gainsbourg and Ned Birkin, who played siblings in this film, are cousins in real life. Ned is the son of the film's director, Andrew Birkin, Charlotte's uncle.
London City Airport was not long opened by 1993 - is why in so many scenes you can hear jet-engines on the LCY taxi-way.
Although she played a teenager, Charlotte Gainsbourg was 21 years old when this film was shot. Her age is not mentioned in the film, but the character is 17 in the book. Andrew Robertson was 18 playing a 14/15 years old.
