I wasn't able to retrieve the actual article text — the content provided is just the site's navigation/header ("Music Film Travel Art News Shop Mailing List") with no article body about Christopher Nolan's 2000 film mistake. I don't want to fabricate details about what the "mistake" was or which film (likely *Memento*, but I can't confirm without the real text).

Could you paste the full article body, or I can try fetching the URL directly if you'd like me to attempt that?
