I ordered the Lego Batman Commemorative box on e-bay and just received it today. It does indeed make a sound that is triggered by a button in the box directly above Joker. The sound quality is pretty good and it is the laugh of Mark Hammil as the Joker. The box itself is very nice, I was expecting the packaging itself to be rather cheap and flimsy but was surprised and happy to find that the quality of the packaging is top notch. It is very sturdy and the design and artwork are both fantastic. Overall I am very excited to have this rare collectable even if it did cost me a pretty penny. Hope this answers any questions you might have.
