In a deleted scene we find out that Charles, Matthew and Fiona were at university together, Gareth was a lecturer until he released a paper entitled "King Lear: Grandpa goes gaga" and Scarlett was found under Charles' kitchen table after a party and has lived there ever since.
Jeanne Tripplehorn was originally slated to play Carrie, but had to back out for personal reasons, following the sudden death of her mother. Andie MacDowell was cast two weeks before shooting began.
Inspiration for the film came when writer Richard Curtis was flipping through some old diaries and realized that he had been to 72 weddings in 10 years.
Andie MacDowell waived a fee for appearing in the film, taking percentage points instead. This netted her an eventual $2 million, compared with Hugh Grant's salary of $100,000.
Originally scheduled to be filmed one or two years earlier, but was held back. When it finally got the green light, PolyGram cut the original budget of eight million dollars to six million.
When star Hugh Grant (and then partner Elizabeth Hurley) showed up at the London premiere of this movie, Hurley's seductive Gianni Versace outfit drew most of the media attention away from Grant, much to his obvious chagrin.
