this project got financing from StudioCanal and Twentieth Century Fox. The adapted screenplay was written by Kassovitz and screenwriter Éric Besnard. Production was initially slated to begin in February 2006 in Canada and Eastern Europe. Casting French actor Vincent Cassel was initially sought to be cast in the lead role. In February 2006, actor Vin Diesel entered negotiations to star in the film, titled Babylon A.D., dropping out of the lead role of Hitman in the process. Filming The shooting schedule was slated to begin in June 2006. By February 2007, filming was slated to wrap in April to release Babylon A.D. in time for the coming Thanksgiving. In February, filming took place at Barrandov Studios. In March 2007, the filming crew, having shot in the Czech Republic, took a two-week hiatus to deal with uncooperative weather, such as the lack of snow, and problems with set construction. Crew members scouted Iceland for locations with snow to shoot six to eight days of footage, which was supposed to be done in February. Filming was also done with the leads Diesel, Michelle Yeoh, and Mélanie Thierry in Ostrava in March. The French visual effects company BUF Compagnie was contracted to develop the film's effects under the supervision of Stephane Ceretti. In April 2007, Babylon A.D. was reported to be over-budget and three weeks behind schedule. A lack of snow meant a skiing sequence to be shot in Eastern Europe had to be moved to Sweden. Later in the month, actor Lambert Wilson was cast into the film. Filming was completed in May 2007.

A French language documentary of the troubled creation of the film entitled Fucking Kassovitz was released in 2011. Music The music of Babylon A.D. was written by Icelandic composer Atli Örvarsson.
