The actor and comedian is partnering with New York art dealer /*David Zwirner*/ on a benefit auction called "Artists for Haiti." It's scheduled for Sept. 22 at Christie's auction house.
Some of the artists who've already donated works include /*Chuck Close,*/ /*Paul McCarthy,*/ /*Jasper Johns,*/ /*Dan Flavin*/ and /*Jeff Koons.*/
Christie's says the proceeds will support nonprofit organizations such as Architecture for Humanity and Partners in Health.
The artworks will be shown at Zwirner's gallery in early September.
/*Stiller*/ established the Stiller Foundation in 2010 to help promote the education and well-being of Haitian children. It is rebuilding four earthquake-damaged schools in Haiti.
