I am forbidden to reveal how this was done and it would be wrong for anyone in the film to actually take credit. These things take months of planning. Most places forbid you from putting anything in the water supply -- and I am not saying anyone involved in the film actually did anything remotely related to such action. Did you know though that there are already over 300 real-life Superheroes patrolling the streets of this great land? And yes, sometimes they get their nose broken.
You say you are not aware yet, what I am speaking about, when I say SUPER? It opens on April Fools Day. Seriously.
Thanks to Shade Rupe for the tip!
