He has seen the film and has had this to say:
"I went up to London yesterday to see the completed Dredd film. I’ve had reservations about certain aspects of it, and made them plain to the team at DNA. All but one of them – a little quibble at the beginning – have been addressed. And what a lot they’ve added. Music is on the button. SFX are excellent. Filming is impressive. I’ve not seen a modern 3-D movie before but I like it. I found myself reaching out trying to touch things that were dancing before my eyes.
Karl is a great Dredd and Olivia gets Anderson completely. This is Dredd as it should be done – true to character, visceral, unrelentingly violent (but not off-puttingly so). It will open, I believe, sometime in September. No doubt you’ll let me know what you think when you’ve seen it, but this has my recommendation."
Wagner is no Alan Moore when it comes to refusing to have anything to do with the adaptations of his work, but he's unlikely to sign on with such enthusiastic support if the film was a dog (which, let's face it, was the unequivocal fate of the Stallone effort from the 90s).
We have also been treated to the first poster for the movie, and a couple more stills.
I'm encouraged by the SFX as Dredd stalks out of the hangar in the first shot.
From what I've heard, most of the film is restricted to one city block (which is going to minimise the effects budget), but it is pleasing that the likely limited inclusion of the Mega City One vista isn't going to feel like a weak link.
