According to director Susanne Bier, the post-production of the film was complicated by the need for dialogue dubbing, due to airplane noise during the shoot in Prague. Jennifer Lawrence was unable to show up for dubbing sessions. The producers of this movie tried to buy Lawrence out of filming The Hunger Games: Catching Fire (2013) for one day, but that proved to be more expensive than the budget of this movie.
Jennifer Lawrence recommended Bradley Cooper for the project. They had worked together previously on Silver Linings Playbook (2012), and they got along so well that they often spoke about working together again in the future. When Lawrence read the script for this movie, she sent a copy to Cooper and asked if he would do it with her.
The project was first announced as directed by Darren Aronofsky and starring Angelina Jolie. They dropped out and were replaced by Susanne Bier and Jennifer Lawrence.
Third project starring Bradley Cooper and Jennifer Lawrence; this is the second time they are playing love interests.
Shot in 2012, after Silver Linings Playbook (2012) wrapped production. The film premiered two years later at the London Film Festival.
