Trivia: Katniss Everdeen and Peeta Mellark are the only Hunger Game tributes ever referred to by their first and last names.

Trivia: After the film was released, director M.J. Bassett (then credited as "Michael J. Bassett") admitted she was extremely disappointed by how the film turned out, and even wrote a blog entry where she apologized to fans who were also disappointed by it. In a later interview, Bassett admitted to second-guessing many of the creative choices in the film, often altering her vision to try and make the movie more broad and appealing for the producers, instead of fighting to make a more personal film with a clear vision. Bassett called the film a "nightmare dance" that she just "couldn't do."

Trivia: Dredd's face is never shown during the film. This is consistent with the comic strips in which Dredd is almost never shown without his helmet and, on the rare occasions when he is, his face is obscured in some other way. Fans were critical of the 1995 Judge Dredd film for the fact that Dredd spent much of the time with his helmet off and his face exposed.
Trivia: When Mrs. Hills is offering Heather her grandmother's necklace, the man standing next to her is Jeff Kinney, the author of the books.

Trivia: During one take of the fight sequence between the Evil Queen and Snow White, Julia Roberts accidentally pulled out some of Lily Collins' hair.
