This is the third story in Roddy Doyle's "Barrytown Trilogy", following the adventures of the Rabbitte family. However, as 20th Century Fox owned the film rights to the Rabbitte name (from The Commitments), the characters had to be re-named in the subsequent film adaptations (The Snapper, The Van).
The movie is set during World Cup 1990, and on at least two occasions, the radio can be heard promoting 98FM. This station did not use this branding until the mid 1990s; it was called Classic Hits at the time.
