In the film Harry Potter and the Deathly Hallows: Part 1, there is one strange detail that significantly differs from the book. Imagine this: Voldemort and his Death Eaters are spreading terror across the country, the Order of the Phoenix is hiding Harry Potter, who is the Dark Lord's most desired target. And suddenly... a wedding. Amidst the grim events, the Weasleys decide to throw a lavish celebration with many guests. But the most astonishing part is that Harry, whose appearance is known throughout magical Britain, walks among the guests without any disguise. This seems like a blatant disregard for safety!
In the film, Harry's protection truly appears minimal—no one is concerned that there might be Voldemort's spies or people under the Imperius Curse among the guests. What about Moody's command to "stay vigilant"? In the book, the situation unfolds quite differently: the members of the Order take security very seriously. The location of Harry's refuge is kept in the strictest secrecy, and on the day of the wedding, he disguises himself as 'cousin Barny Weasley' using Polyjuice Potion to avoid being recognized.
Such a level of secrecy fooled all the guests except Luna Lovegood, who recognized Harry simply 'by the expression on his face.' Seeing how thoroughly the Order of the Phoenix protects Harry in the book, the carelessness in the film seems at least strange. Of course, one can understand the screenwriters, as fitting all the details of the book into a two-hour film is not easy, but this moment leaves the impression that Harry's protection was not well thought out.
Yes, cinema is an art of compromises, but sometimes simplifications contradict the logic of the plot and characters.
