- The Cast Showoff: You wouldn't cast Kaitlyn Dever, include a karaoke scene in your movie, and NOT have her belt out "You Oughta Know," now would you?
- Completely Different Title: In Spanish, the film was released in Latin America as La noche de las nerds ("The Night of the Nerds") and in Spain as Super empollonas, which doesn't even have a direct translation into English. note
- Dawson Casting: Most of the cast of high school seniors are played by actors in their early twenties. Billie Lourd was in her late twenties, and is only 3 years younger than Jessica Williams (Ms. Fine.)
- Irony as She Is Cast: In the film, Amy is a lesbian whereas Molly is straight. In real-life with their actors, it's the other way around: Kaitlyn Dever is straight whereas Beanie Feldstein identifies as queer and is engaged to a woman.
- Method Acting: Before shooting began, Kaitlyn Dever and Beanie Feinstein lived together for a month to help establish a real chemistry between their characters.
- Real-Life Relative: Olivia Wilde cast her then-fiance Jason Sudeikis as the principal.
- Star-Making Role: Both Beanie Feldstein and Kaitlyn Dever had major roles in projects of critical and commercial success before this film, but this proved to be a major boost for both lead actresses.
