The article content could not be retrieved from the supplied text — only the page's navigation menu and site branding were provided, with no actual article body about Diane Keaton or the 2003 film in question. As a result, it is not possible to accurately summarise what the piece says about the film or why Keaton reportedly found the experience humiliating.

To provide a reliable, neutral summary in British English, the full article text would need to be supplied, as fabricating details about the film or Keaton's comments would risk inaccuracy.
