Spielberg, Cruise, Kidman: Hollywood comes to the Olympics

Tom Cruise, Nicole Kidman, Steven Spielberg, Lady Gaga -- there have been plenty of A-listers around Paris for the first few days of the Games. The biggest celebrity draw has been Artistic Gymnastics, arguably the hottest ticket this week as American superstar Simone Biles added to her medal haul. Cruise has received a particularly warm welcome -- given a knighthood from the French government (becoming a "chevalier des arts et des lettres") and serenaded with a blast of the "Mission: Impossible" theme in the arena.
