"When the President is kidnapped, the First Lady, a former Marine, leads a rescue mission to take down the terrorist with direct roots to the White House"

I think Amy is right. Having a movie "greenlit" with a not-too-similar concept doesn't affect anyone else's concepts or projects, especially if they are written well. Fact is, the difference in THIS hook compared to "White House Down" is miles: no one to my knowledge has written a viable concept involving the First Lady. Not only is the tite of WHD a direct rip of "Black Hawk Down", there are dozens of WH-being-taken-over stories, and one great story in "Air Force One" where the President himself is the hero. Don't forget "Independence Day", where the President himself is a fighter pilot to the rescue.

With all of the attention Michelle Obama is getting because of her physical and imposing strength and physique, and the need for strong female action stars to replace the Stallones, Arnold's and Willis' of the world, I can't help but be completely jealous of not having this concept first. And, that is always the mark of a great concept; when a roomful of executives say "Why didn't we think of that?"

wereviking - if a concept is fresh, or potentially "brilliant" as sharkeatingman says, then I would never tell someone to "move on". Ridiculous. It's all in the execution. Keep writing. Make it amazing.

The problem is White House Down or whatever it is called is already in development as a big script sale a month or so back about the president (male) being the ex Army guy who has to bring down the bad guys taking over the White House. A shame, as your idea seems more fresh. But I would advise moving on to the next idea as this just won't go anywhere with a similar film already green lit.
