Hollywood actor Tom Cruise has reportedly left a doodle to his wife Katie Holmes etched in the top spire of the Dubai’s Burj Khalifa while filming stunts for his latest movie Mission Impossible: Ghost Protocol.

Atop the Burj Khalifa, the world’s tallest building, sits a thin, white spire that seems to puncture the sky. This is the highest any person can get on a man-made structure on this planet.

And there, scrawled 15 feet from the very top of the spire, is Tom Cruise’s autograph. His name and a doodled heart with an inscription to his wife, Katie Holmes, and children.

Cruise spent four days filming action scenes for “MI: Ghost Protocol” on the world’s tallest building, and used the Burj Khalifa as the signature set piece in the movie. Now, it seems, he also left his mark on the building.

“The only person who will ever see [Cruis'e art] is the guy who paints the building some day,” the film’s stunt coordinator Gregg Smrz told the New York Post newspaper.

“Fear of falling was the first thought that went through my head when I lunged out of that building,” recalled Cruise, whilst hanging nearly 100 floors off the ground, adding: “ I just really, really hoped I wouldn’t fall ,” Cruise said last week.

Returning to the scene of the ‘crime,’ Cruise was in Dubai once again for the film’s world premiere at the Dubai International Film Festival on December 7, making a dramatic red carpet appearance in front of hundreds of fans and media.

This is the fourth movie in the franchise, which launches in a limited IMAX-only engagement Friday before turning up in theaters nationwide on December 21.

The action star took a break from filming one day to navigate a series of elevators, steep staircases and 200 feet of vertical ladder to make his way to the very top of the building’s spire. He was harnessed and lowered down the outside to make his graffiti. All of this for something that wasn’t filmed and won’t even feature in the movie, reports NGI Context.
