Apologies for the distorted aspect ratio in this clip, but the content is all intact. Here you can see Judges Dredd and Anderson put between a Cityblock and a hard place by Lena Headey's villainous Ma Ma Madrigal.
That's a key bit of set-up that comes pretty early on. If you were wondering how they kept pretty much all of the action in one Cityblock, now you know.
Thanks to Den of Geek for the clip.
