Ford has vehemently denied that rumor on many, many occasions. I’m not sure if I believe him though.
Bud Yorkin has said that if Ford hated the narration and was aiming to make it unusable, he’s never intimated that to him. Apparently Scott wasn’t opposed to the idea of a narration, it was the style narration delivered by Ford that he opposed.
