The last name of the bride's family is Peyser. Penny Peyser played the bride in the original The In-Laws (1979).
Working title was "'Til Death Do Us Part"
Originally released to the public in trailers and previews as The Wedding Party in early 2003, and yet was touted as a remake of The In-Laws (1979). Eventually the film was renamed.
Composer Lalo Schifrin wrote a score that was mostly unused. However instead of hiring another composer after Schifrin left the project the director and/or producers decided to use the temp-track selections written to previous movies by various film composers and these composers got credited instead of Schifrin who went on being uncredited even if some of his work is still in the movie.
