Question for movie buffs: Was scripting/filming in the works for this movie before Bin Laden was killed? It seems like the raid could've easily been added on after it happened. It's just incredible to think that this entire movie could've been written and filmed in only a year and a half. Fantastic!
They were actually working on the film before Bin Laden was killed. The movie was going to focus more on the hunt for him. When Bin Laden was killed, they revised the script and, clearly, the ending.
As far as some folks thinking the beginning of the movie drags, there are others who actually praise the CIA sleuthing portion of the movie more than the final assault (seen as some as anti-climactic). People who think this is a pure action movie are going to be disappointed, imo.
Finally, I'm always amused at the criticism of The Hurt Locker as not being completely realistic from a technical point of view. After all, it is a movie made for entertainment and not a documentary. There is no way, for example, that a movie audience would watch two hours of guys working on a single bomb. As long as the essence of the story and experience is conveyed, it serves its purpose.
