One of Hollywood's most loved and versatile actors, Jack Black is back with yet another stellar role in his next - The House with a Clock in its Walls. He is seen playing a wizard and creating an entirely magical experience on the big screen. To ensure he got the character and its nuances down pat, he decided to learn the "tricks of the trade" from none other than master puzzle and illusion maker David Kwong.

Kwong who's an ace with building illusions for film and TV imparted some of his knowledge and tricks to Jack Black himself. To create and deliver that skilful deception or what's referred to as the quintessential sleight of hands in the wizardry world, Black knew he needed to learn what it means to perform what we in India call - haath ki safai. Talking about taking up a few lessons magician and illusion creator David Kwong, Black said, "it all really comes down to fingers and hand dexterity and I learned from a master David Kwong."
