Trivia: American Idiot
- Hey, It's That Guy!:
- The music video for "Wake Me Up When September Ends" stars Jaime Bell and Evan Rachel Wood.
- The video for "Jesus of Suburbia" has Lou Taylor Pucci and Kelli Garner from Thumbsucker as Jesus and Whatsername (Garner reprised the role for the unreleased video of Whatsername).
- The musical has John Gallagher Jr. from Spring Awakening as Johnny/Jesus and Tony Vincent from We Will Rock You as St. Jimmy. Inverted when Billie Joe filled in for (and eventually replaced) Vincent as Jimmy. Davey Havok from AFI also filled in for Billie Joe once.
- Hey, It's That Voice!: Kathleen Hanna (of Bikini Kill and Le Tigre) sings the opening to "Letterbomb"
- Unintentional Period Piece: The title track captures a lot of the despair many young left-wingers felt at the seeming invincibility of the Republicans and George W. Bush in the '00s.
