Sorry to double post, but also,
The Dredd pinball game was made by Bally Midway, which has since been bought out by Warner Bros.
Other Dredd games were published (and are presumably still owned) by Virgin (which was bought out by Interplay, who is now selling its assets), Atari (owner of the Melbourne House and Gremlin Interactive libraries), Tin Man Games, and Kuju Entertainment.
Throwback Entertainment currently owns most of Acclaim's game titles. Perhaps they own Acclaim's Dredd games.
Also, a company called FarSight Studios put a game called
The Pinball Arcade on Steam, which includes a Dredd board.
Rebellion does outright own Dredd vs. Death and Dredd vs. Zombies.
