Hey! These people are putting in free time and free equiptment.
If I had the money I would make it a short.
In my experience, this sort of thing is much more commonly done by directors who are pitching their "take" on a film rather than writers trying to sell a script.
I saw a "trailer" for a script of mine -- not done by me, but by the director that they ultimately attached that he cut together from bits and pieces of other movies to give them a sense of how he imagined the movie, albeit it was simply made up of pieces of other movies.
But on some level, it obviously worked. It gave them a sense of what sort of visuals he was thinking about, what other movies he was referencing, his cutting style, his ability to create a sense of emotion.
The point is, though -- that all of that really has to do with *directorial* ability -- not script writing.
And the fact that he was simply cutting stuff together from other movies meant that he was able to muster some pretty high-end production values without spending a dime. What difference did it make that it was all borrowed footage -- it wasn't meant for anything other than for him to use to give a handful of producers a sense of how he imagined the movie to be.
These sorts of things -- trailers, concept art, all that sort of thing, *can* be helpful, but only if they are produced at the highest professional level.
So the question is not -- do you have professional equipment but rather -- when you go to the theatre and watch trailers of the sort that really knock you dead -- like the trailer for Batman where that big truck does a back flip -- I'm talking about trailers where the audiences are applauding the trailer.
If what you're making isn't one of those trailers, if it isn't that good, if it's not going to accomplish that, then think carefully.
And if you're saying -- well, my movie isn't like Batman, it doesn't have those kind of "truck-flipping" moments -- then the question is -- what are the thirty seconds or the sixty seconds in your hundred or hundred and ten minutes that are going to make people want to see your movie?
And can you really pick out those sixty seconds and shoot them with a sufficiently high degree of professionalism that some extremely jaded people will watch it and want to read your script based on it?
Personally, as somebody who used to work in development, those kinds of things never really impressed me.
I'll tell you what impressed me.
First, if I read a logline and thought, "Damn, that's a great idea. I wish I'd thought of that."
Second, if I started to read the script and by the end of page one, I was already involved in the story and I stayed involved right through to the end, which perfectly resolved everything that came before.
And for strictly commercial reasons, scripts should be star castable. If your script can't attract a name actor, the chances of it getting financing is extremely small.
If it can do all of these, then your script has a shot.
