Reisch says there are "major sequences missing" from the final film. "After he'd seen it, Zanuck simply couldn't accept the fact that the police at Niagara Falls were of Canadian extraction. We had British actors playing Canadian police commissioners and detectives and various cops, and he just abhorred it. He wouldn't let us go back to the stages to finish it or to repair it—no, he just took it out! The American audience, he said, does not know, does not understand, that the Niagara Falls are bisected by the border . . . and we should have used Americans. And Henry Hathaway, who didn't like the idea either, sided with him. So there are big holes in the story."
