Relentlessly self-promotional, clearly cynical, yet with some useful ideas: Blake Snyder's book Save the Cat! — The Last Book on Screenwriting That You'll Ever Need (2005) discusses how to produce a "successful" movie script. (The result may not be art, but it may have a better chance to sell to Hollywood.) Summarizing the adroit summary of the book by Phil Gyfford:

• What is it?

Describe what the movie is about in one sentence. The "logline" should present something unexpected ("The Hook"), elicit a compelling mental image, suggest the target audience and cost of the film, and provide a "killer title".

* Give me the same thing ... only different!

Identify what film genre your idea fits into; Snyder suggests 10 categories and calls them: Monster in the House; Golden Fleece; Out of the Bottle; Dude with a Problem; Rites of Passage; Buddy Love; Whydunit; The Fool Triumphant; Institutionalized; Superhero.

* It's about a guy who ...

Create a hero — someone with whom the audience can identify, and who has a compelling goal, is "demographically pleasing", and can support the plot development. Five archetypes whom Snyder suggests are: Young man on the rise, dumb, plucky; Good girl tempted, pure, crazy; Clever and resourceful child; Sex goddess; Hunk.

* Let's beat it out!

Snyder defines a 15-step template for any script's story arc: Opening Image; Theme State; Set-up; Catalyst; Debate; Break into two; B story; Fun and games; Midpoint; Bad guys close in; All is lost; Dark night of the soul; Break into three; Finale; Final image.

* Building the perfect beast

Use a storyboard with 40 index cards, one for each major scene.

* The immutable laws of screenplay physics

Save the Cat: make the hero immediately likeable * The Pope in the Pool: do any necessary exposition in a surprising context * Double Mumbo Jumbo: never have more than "one piece of magic per movie" * Laying Pipe: minimize set-up time before the story gets rolling with the Hook * Black Vet a.k.a. Too Much Marzipan: don't overdo a bright idea * Watch Out for that Glacier!: make danger come fast and violently * The Covenant of the Arc: "Every single character except the bad guys must change over the course of the movie. If the story's worth telling it must be life-changing." * Keep the Press Out!: build the story within the family or neighborhood; avoid media or other outsiders

* What's wrong with this picture?

Make the hero active * Show, don't tell * Strengthen the bad guy * Intensify and accelerate the plot as it proceeds * Evoke diverse emotions throughout the story * Let dialogue reveal each character's qualities * Give the characters plenty of room to change during the story * Be sure the characters are distinctive * Force goals to be primal

... though of course, to write well one must transcend — and as poet Robert Pinsky says, "There are no rules. However, principles may be discerned in actual practice ...".
