Tom Cruise could be in a spot of bother with the authorities when he returns to Dubai this week. News reaches us that not only did Cruise perform a variety of daredevil antics atop the Burj Khalifa last year, but the actor also added his own bit of high-altitude graffiti. Having climbed to the very top of the skyscraper for a photoshoot, Maverick then asked to be lowered down by a rope 15 feet over the edge so he could autograph the building. "The only person who will ever see that is the guy who paints the building years down the road," says the stunt coordinator Gregg <span style="font-size: 10pt; font-family: Arial;">Smrz, who was the man holding the rope. Surely this has to be considered as a Guinness World Records entry for highest tagging? And surely the full force of the law needs to be brought against Cruise for defacing a national monument..</span>
