PARIS - SEPTEMBER 22: French actor Christophe Heraut plays Ben-Hur and rides in a Roman chariot during the stage production premiere of 'Ben-Hur' September 22, 2006 in Saint-Denis, Paris, France. After Charlton Heston played the lead in this sword and sandal epic, written by Civil War Union Gen. Lew Wallace, on the big screen, the play is set to return in a live version staged at France's biggest sports stadium. Behind the 13-million-euro (16.5-million-dollar) show is a veteran Paris-born director Robert Hossein, who involved a large crew of hundreds of actors for the show.
