While the film was released wide in 2011, it had a few screenings at film festivals in late 2010. At that point, it could have been considered a science-fiction film, due to most of the story taking place in 2011.
Screenwriters Luc Bossi and Laurent Turner enjoyed working together so much they quickly re-teamed for the thriller The Prey (2011). Their method involves discussing the story together, then having Turner write a draft, after which Bossi goes over it, correcting it, adding new scenes, removing others, and handing it back to Turner so that he goes over it and so on until the two are satisfied and send the script to the producer and director.
