Mysterious Umbrella Man pops up around Budapest performing amazing stunts at death-defying heights as the main character in Hungarian photographer Péter Kálló's Balance Project. After being spotted atop the Ferris Wheel and Budapest bridges, Umbrella Man has now climbed Buda Castle to see the sunrise – and to show Will Smith how it’s done. Earlier this summer, the Hollywood actor scaled Chain Bridge as part of the "In My Feelings" challenge and posted a video on his Instagram page. In reaction, Umbrella Man has just issued a cheeky message, claiming that he has now outshone the star with this extreme performance, captured in amazing photographs by Péter Kálló.

“Hey @willsmith, it's me, The Umbrella Man and this is my response to your #kikichallenge! Climbing out of a little window and dancing on the roof is no challenge for me
