Idea Workshop
Rejection is a fact of life in Hollywood, so if your idea was not selected (an oblique way of saying rejected), we understand your pain. And while we cannot provide feedback on specific ideas, we can offer some general advice. Here are some common reasons for rejection:
Too familiar
Your idea was just too similar to other ideas bouncing around Hollywood. This can be perplexing. You see bland, trite movies at the multiplex and figure (rightly) that your idea is much better than the junk being made. Then you conclude that your idea is superior to the ideas being pitched, and that is where you are wrong. There are great ideas being pitched that never get bought or made into films -- it's just a weird quirk of the business. The competition is tough.
Too general
We see way too many ideas that are so general they do not suggest a story. Examples: "Two guys drive across country having adventures"
"Fred and Mike drive their Corvette from Jacksonville to San Francisco having adventures along the way." The second version is no better, even though it has more apparent details. This would not work either: "Two Lane Blacktop" meets "Thelma and Louise."
Or this: "a man hires a beautiful woman to be his secretary because he wants a romantic relationship with her." That does not suggest a story, just a situation and a common one at that. How about this instead: "a skirt-chasing boss unwittingly hires a gorgeous transvestite as his secretary and falls in love with her (him)."
That would be better, but it still lacks a twist to add conflict and make it fun. Perhaps "a skirt-chasing boss unwittingly hires a gorgeous transvestite as his secretary and falls in love with her (him), and confides some of his dirty business secrets. When the boss discovers the truth, he also discovers the transvestite is the son of the chairman of the board and cannot fire him." That is still kind of lame, but you get the point.
Good but not pitchable
Sometimes ideas are great, but they are not pitchable ideas because they rely too much on execution. For more on this, read Pitchable vs. Unpitchable under What is a Good Idea?
