Q: In the movie Deathly Hallows Part 1, Harry Potter did not disguise himself using polyjuice potion at the wedding of Bill and Fleur. But in the book he was disguised as a cousin of the Weasleys, Barny Weasley, because there were threats.  Shouldn't he have disguised himself, as Death Eaters might be around looking for him? Why did they not take that matter seriously in the movie?
