Very cool update. Also includes a new "laughing" portrait and just about every weapon he used in the movie. The costume is better, unbelievably. I didn't think the original DX Joker could be improved upon but this is Hot Toys.
If only they'd take another stab at Harvey Two-Face. Far and away the weakest offering from their original Dark Knight line.
