I don't think you can name a good picture where the production or the possible promotion isn't "cast-contingent." That means the film needs not just star power but star box office power.
Larry GelbartI love to play with language; make it do tricks, turn a word inside out to see if it's got a hidden meaning tucked away somewhere, or perhaps find that it's capable of an extra entendre or two. . . . Plotting is nothing I did, or do, naturally. It is the hardest part of the writing process. No matter how many times you plot a script successfully, the next one, representing new and uncharted territory, convinces you that you really don't know how to do it at all.
