- Acting for Two: Jennifer Tilly plays both herself and voices Tiffany.
- Actor Allusion:
- John Waters plays a photographer, just like the titular character of his film Pecker. His death, involving acid getting splashed on his face, is similar to what happens to Dawn Davenport in his film Female Trouble, where she gets splashed with acid, scarring her face. Unlike Waters' character, Dawn survives.
- Jennifer Tilly's lobbying for the part of the Virgin Mary echoes a scene from a Christmas Episode of Family Guy. In the episode, her character, Bonnie Swanson, plays the part of Mary in a play about the nativity.
- California Doubling: Partially filmed in Romania of all places.
- Creator In-Joke: On the film set, Tiffany's arm comes loose and grabs the floor manager's crotch. In Bride of Chucky, Jennifer Tilly joked on the DVD commentary that the Chucky puppet kept grabbing her breasts.
- Fake American: In-universe. Jason Flemyng plays himself putting on an American accent for the Chucky movie he's starring in. When they stop filming, he reverts to his natural English accent.
- Fake Brit: Billy Boyd is Scottish and uses an English accent to play Glen.
- Irony as She Is Cast: Joan is a low level assistant who is desperately writing fan mail to celebrities. She's played by Hannah Spearitt, who had just come off her time in S Club 7, a worldwide famous pop group.
- Jossed: TV spots had to contain the disclaimer that "Britney Spears Does Not Appear In This Movie", as her management were concerned that people thought Britney played herself. A lookalike plays her in the cameo.
- Old Shame: Jason Flemyng has said this is the only film he'd erase from his resume.
- What Could Have Been:
- Redman's As Himself role was originally written for Quentin Tarantino.
- Producers were torn on giving Glen his own look or having him resemble Chucky. They settled on a compromise - where he was given blue eyes, red hair and freckles in a different shade to his father.
- Chris Sarandon was approached to reprise his role from the first Child's Play film but had to turn it down due to a schedule conflict.
