10 Things Captain America: Civil War Will Have To Change From The Comic

3. The Negative Zone Prison

What Happens In The Comics: When the Stamford Disaster struck, Tony Stark and Reed Richards met to create a list of 100 possible ways of dealing with the aftermath. One of the more disturbing solutions they implemented was the 42nd on the list. Prison 42 was a secret containment facility in an alternate dimension called the Negative Zone. Not only was the prison created to hold superhuman prisoners, but anyone who escaped would be trapped in a desolate, lifeless universe with no hope of returning to Earth. Any character, hero or villain, who opposed the Superhuman Registration Act was to be held there indefinitely and without trial. The introduction of the prison cast Iron Man and his allies as authoritarian at best and fascistic at worst. In a story where the allegiances of readers were as important as those of the heroes, this was a significant step. Why It Won't Work In The Film: As with the inclusion of elements like the New Warriors, Marvel won't be able to use the Negative Zone because it doesn't exist in the Marvel films. So far, the only parallel universes explored in the films have been the other realms from the Thor films. In fact, the closest thing to the Negative Zone would be Svartalfheim, the titular realm featured in Thor: The Dark World. While Prison 42 could be built here, it seems unlikely if Thor isn't appearing. Of course, the Civil War movie could simply use a normal prison. But even a specially-designed super prison wouldn't be as significant, or downright twisted, as sending objectors to another dimension filled with nothing but endless hordes of giant insects.
