Whilst filming at the Park Lane Hotel, on Park Lane in London, some 30 extras had to be called in at short notice when the production team noticed the frequency of passing red double-decker buses, a common enough occurrence in London, but not in New York, where the scene is set. The extras were used outside the hotel to try to block the buses out.
In an interview in Newsweek Magazine (May 5, 2008), Patrick Dempsey mentioned shooting a nude locker-room scene for "Made of Honor." This scene was cut from the release print in order to preserve the PG-13 rating.
The Spanish subtitles in theaters changed the name from Made of Honor to "Quiero Robarme la Novia". This translates in English to "I want to steal the bride".
