Until a major company has made an offer there is no way for anyone here (or you for that matter) to answer the question. Would you really turn down $600,000 for your script just because it might not turn out how you have it in your head?

Fun to talk about, but until the check book is open and a famous director is telling you how much he loves yours script there is no way to truly know how you (or anyone) will react.

How about selling this script to a major company and using the money to make another script?

The aim of an argument or discussion should not be victory, but progress.
Joseph Joubert, essayist (1754-1824)

Joseph has a good point. $600,000 goes a long way. I went to school with a guy who made it to the last cut off for the Project Greenlight Script Writing contest. Didn't win, but with the press later got $25,000 for it. So it does and can happen that way.

Put it out there!

If nothing comes of it you might as well make it. If someone offers you big bucks then give it to them. Even if you're not in it for the money, once it's out there you'll get a name for yourself.

If you make it on your own, there's every chance it wont see light of day.

you could sell it with one rule: "I'll sell it to you but only if I can direct it" Allow them to hire all the other people but you want to direct it. However you will need some backing to show that your not just gonna kill the project. If they are gonna invest theyre money in the project they are gonna want to make sure you do a good job. So make a couple shorts that are similar in feel and genre to yuour feature and put everything you got into them. Then you have at least some sort of track record. But then again if they offer a large enough figure for your script and they wont let you direct it, just take the money. Then use the money to make another movie.

"Anyone who has ever been privileged to direct a film also knows that, although it can be like trying to write 'War and Peace' in a bumper car in an amusement park, when you finally get it right, there are not many joys in life that can equal the feeling." - Stanley Kubrick

You have to be realistic. Whether you think the script you wrote is good or not, that in no way affects the attitudes of others in the film business. What I mean by this is that many good scripts get turned down, if they are looked at at all, because of a difference of opinion in visualizing how the script would play out. Also, look how many crap movies are made. People just have their own opinions.

But my advice is to make a low budget version of the film on 8mm or DV or something cheap like that, then you submit it, with your script, to either a film commission or major film company. This allows you to show how you want the script to transfer onto film. This helps the people who watch it see the film with your ambitions, instead of reading mere words and forming their opinion. I call this the visual aid technique. Besides, whether you get a grant, sell the script, or do nothing of the sort, you still have your own film to send to film festivals and watch for your own enjoyment.
