Famous quotes containing the word john:
“Well, I know you haven’t had much experience writing and none at all in pictures. But I’ve heard about you. It all sounded like you’re just the man I wanted for a story about the Navy. I don’t want a story just about ships and planes. I want a story about the officers.... I want this story from a pen dipped in salt water not dry martinis. Do you know what I mean?”
—Frank Fenton, William Wister Haines, co-scenarist, and John Ford. John Dodge (Ward Bond)
