Trivia: Jersey Girl
- Titled After the Song: The Bruce Springsteen cover of Tom Waits' original from Heartattack And Vine plays over the end credits.
- What Could Have Been:
- 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 George Carlin 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 called him the next day asking 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 the heavy emotion of the scene began to make him physically ill. It was rejected when test audiences started laughing.
