Jennifer Lawrence does not actually sing in the movie - she's lip-syncing to session musician Sarah Rayne's voice. However, she did record her own version of one the songs, "All You've Gotta Do is Love", which was described as "not half-bad."
The film's release was moved from April 2012 to September 2012, allowing Jogos Vorazes (2012) to be released without this film being released the same month as originally planned.
The film was shot in the 2-perf Techniscope format to provide a grainy image reminiscent of older horror films and to save money on film stock and processing. Despite this, "Filmed in Panavision" is listed in the end credits.
Producer Aaron Ryder had Jennifer Lawrence read for the lead role based on her performance in Inverno da Alma (2010).
The project was originally announced in 2003 with Jonathan Mostow directing and Richard Kelly scripting.
