Apparently, the man on the box art of the European version of Broken Sword: The Shadow of the Templars has nothing to do with the game, but is a real-life image of a criminal on death row, just before he was executed. The creators of the game chose the image because it looked sinister.
The game was re-titled "Circle of Blood" in the U.S., as it was thought that Broken Sword was a title that would not sell.
