Ben Stiller is auctioning a walk-on role in his upcoming comedy Neighborhood Watch to raise money for charity.
The winning bidder will be invited to the Atlanta, Georgia set in December (11) to shoot a scene alongside Stiller and his castmates Vince Vaughn and Jonah Hill.
The CharityBuzz auction is expected to pull in as much as $20,000 (£12,500) when it ends on Tuesday (22Nov11) and all proceeds will benefit the Stiller Foundation, which helps provide education for underprivileged children around the world.
