When Noomi Rapace was cast, she suggested Rachel McAdams for the role of Christine, because they had worked together on Sherlock Holmes: A Game of Shadows (2011) and wanted to repeat the experience, this time with plenty of on-camera interaction.
This is a remake of the French film Love Crime (2010), directed by Alain Corneau, who died the same year this film was released.
According to Brian De Palma, the lead actresses arrived in Berlin a week before shooting started to rehearse the screenplay and had a lot of suggestions for the relationship of the characters, including making the lesbian subtext a more obvious element of the story. De Palma found himself overwhelmed with changing the screenplay so close to shooting, so he brought in Natalie Carter, co-writer of Love Crime (2010) by Alain Corneau, on which Passion (2012) is based on, and she re-wrote some scenes to accommodate Rapace and McAdams.
This is the seventh film by Brian De Palma that composer Pino Donaggio has scored. Their first collaboration was Carrie (1976).
Marks the second film Noomi Rapace, Rachel McAdams and Paul Anderson starred in together, only a year after Sherlock Holmes: A Game of Shadows (2011).
