One of Jackie Chan's most enduring and popular movies of all time is without a doubt Project A - a period piece in which Jackie takes on a group of villainous pirates, it features some wonderfully choreographed fight sequences and a fantastic bicycle chase through the cramped alleyways of the town. Most memorable - and undoubtedly one of Jackie's craziest stunts - is the clock tower fall, in which he plummets down several stories with nothing but a couple of flimsy-looking canopies to break his fall. Not content with his first take, Jackie filmed it a second time. Then a third. Unsurprisingly, on one take he nearly broke his neck, as you can see from the outtakes below. https://www.youtube.com/watch?v=Yj0zNIUNLTo
