Raise the Titanic 

Look you obviously have a very thin skin and also an inability to write clearly and concisely in English. So >with a sigh< I have to take your hand and walk you through the facts:
you quote the opinions of just one screenwriter yet there were 17 other writers. Consider WP:UNDUE
you also insist on saying that they didn't ask for a credit for the film. Well so what? There were 17 people who also wanted a credit and in the end only one got it: Adam Kennedy. WP:SPADE
you use three sentences when I wrote it up in one. Do you know what a tautology is?

You want to keep this:
Novelist Larry McMurtry - who disliked Cussler's novel considering it "less a novel than a manual on how to raise a very large boat from deep beneath the sea" - claims that he was one of approximately 17 writers who worked on the screenplay..

Then there is this:
Novelist Larry McMurtry, who was one of 17 screenwriter who offered to work on the screenplay, disliked Cussler's novel. He considered it "less a novel than a manual on how to raise a very large boat from deep beneath the sea".

He doesn't claim anything, he was a writer on the project!

In the end if you don't want grief then my advice is walk away now? There are no rewards for this, none whatsoever, except unwarranted self importance and eventually a chance to advance to a new level. Despite my crass manner I am trying to be nice, but others who play here will not.
