Dredd is probably considered 'toxic' by the money men so no chance of a sequel there. Not yet anyway but something like a Mad Max clone, some future cop having to cross the desert to do whatever a Cop's gotta do will inevitably be made. Very badly made I assume. Asylum Pictures will make a cheapy rip off for the Scy Fi channel and other 'original' projects, like re imagining Damnation Alley, No Blade of Grass,The Postman even will embarrass themselves at your local theatre soon.
