* TitledAfterTheSong: The Music/BruceSpringsteen cover of Music/TomWaits' original from ''Music/HeartattackAndVine'' plays over the end credits.
* UnderminedByReality: A bit of an unusual case. Originally the plan was to advertise the movie as being all about the relationship between Affleck and Lopez's characters, making Lopez's [[spoiler:death]] early on a huge shock. But by the time it was released ''Film/{{Gigli}}'' and the general public being utterly sick of them as a couple had killed this plan's viability, so the twist was put right in the trailers, leaving the film with little real identity of its own.
* WhatCouldHaveBeen:
** Jason Mewes was going to play Ollie's assistant, but was in rehab after he and Kevin Smith had a serious falling out.
** While Bart had aways been written with Creator/GeorgeCarlin in mind, Carlin had originally asked Smith to write him his dream role: a clergyman who strangles six children. When Smith sent Carlin the script, Carlin, true to form, called him the next day asking [[CrossesTheLineTwice why his character doesn't strangle the little girl]].
** The scene where Ollie finds out that Gertrude died in childbirth originally ended with him vomiting on the floor because Ben Affleck was so lost in character that [[TheMindIsAPlaythingOfTheBody the heavy emotion of the scene began to make him physically ill]]. It was rejected when [[RealityIsUnrealistic test audiences started laughing]].
