In order to fine-tune her character Suzie's British accent, Alison Brie listened to recordings of readings provided by her British co-star Emily Blunt.
The trivia items below may give away important plot points.
In early trailers for the movie, just before Emily Blunt is shot in the leg with a crossbow, you hear the little girl say "I'm Pocahontas." In later trailers, to play off the anticipation and success of The Hunger Games, it was changed to "I'm Katniss." The Pocahontas reference was kept in the finished film.
The dress that Violet wears during her wedding is Valentino. It is also one of the dresses featured in the magazine she looks through earlier in the film.
