Aldrich says the script was almost entirely written by Hugo Butler but Butler does not get credit due to being blacklisted. Aldrich said "There are optimists in the society, not many left, who thought that someday those guys the Hollywood Blacklist would get post-mortem credits for their work. So he wrote "World for Ransom" and I put my name on it to try and get him the credit. And it went into arbitration with the Writer's Guild, and another guy Lindsay Hardy got total screen credit on it. It was a joke. He no more wrote that script than walk on the water. Butler made that total screenplay."
