Will Smith did not physically climb to the top of Burj Khalifa. However, there is a scene in the movie "Hancock" where his character is shown climbing the building, but this was achieved through the use of special effects and CGI.
Video shows Will Smith climbing to the top of the Burj Khalifa
In the movie, Will Smith's character, John Hancock, climbs the Burj Khalifa, which is the tallest building in the world, as a way to prove his powers as a superhero. However, in real life, the building is not climbable and it is illegal to do so. The filmmakers used special effects and computer-generated imagery to create the illusion of Hancock climbing the building. The scene was shot on a soundstage and the building was added in post-production.
Yes he did.
But a much cooler picture is that of Tom Cruise who did it while filming “Mission Impossible: Ghost Protocol”. Barefoot and relaxed, he looks - unlike Will Smith - that he has no safety equipment on (though surely he did!).
