FilmUp on Instagram: "‘In Who Am I? (1998), Jackie Chan performed one of the most dangerous stunts in film history. He slid down the glass façade of the 24-story Willemswerf building in Rotterdam — without a stunt double and without visible safety wires. The stunt was so risky, he postponed it for days due to rain and wind. But when the weather cleared, Jackie did it himself — risking his life for the perfect shot. For the initial slide, Jackie Chan performed the stunt without any safety wires.
