Video game-to-movie enthusiast Uwe Boll had already acquired the film rights to Far Cry the video game from Crytek before the game was even released (and subsequently became a smash hit, spawning several sequels), which explains how such an unsuccessful director had been given permission by Crytek to handle such a anticipated project. The film was budgeted at £30 million but took in less than $1 million at the box-office.
Celebrity chef Anthony Bourdain visited the Far Cry set in Vancouver during a taping of his show Anthony Bourdain: No Reservations (2005). This explains how Bourdain came to be cast in the small (and uncredited) role of a scientist who gets shot near the end of the movie.
