Re: Who will be the first superhero to die on film?
Hulk in the tv film The Death of the Incredible Hulk.
If we go more recent
In X-men: Days of future past= We might see numerous characters die depending on cameos .
The Avengers 2 = If a member of the team dies I think it will be Hawkeye.
The Man of Steel 2 or 3= We could see a loose adaptation of The Death of Superman storyline.
