New Dark Knight featurettes online

Two new Dark Knight featurettes have gone online over at , and they're ace.

You get to see a behind the scenes look at the making of the Joker's masks, and watch a decent Imax exploration - which has the odd snippet of new footage.

Oh, and if you pause it at around the 2.23 mark, spoiler alert, you get to see something iconic, belonging to Harvey Dent. We can't wait for this film.
