Given a paragraph about movies, and a set of conversational question answers about the paragraph, generate a relevant question to the topic of the paragraph. The paragraph has the prefix 'CONTEXT:'. Each conversation question has a prefix `Q:` followed by the answer prefix `A:`.

Let me give you an example: CONTEXT: The balance of power had shifted considerably since the first set of quotes. King Joffrey is dead, and his younger brother Tommen is now king. Unlike his wild card of an elder brother, Tommen is gentler and more prone to manipulation by his new bride. The Lannisters impeccable image has also been shattered. They failed to prevent the assassination of their king in the midst of his own wedding day, and the suspected assassin is the king's Lannister uncle. Not only do they look incompetent, they are divided among themselves. On the other hand, the Tyrells' situation is much stronger now. Tommen is already wrapped around Margaery's pretty little finger, and she knows that the assassination was orchestrated in part by her own family. In Margaery's eyes, the Lannisters look disoriented and lost. Putting on a show trial for one of their own, whom she knows is innocent of any wrongdoing. Whatever power Cersei held over Margaery has now been diminished. <sep>  Q: What was Margaery's motivation to call Cersei 'sister' again? A: Whatever power Cersei held over Margaery has now been diminished.
The answer to this example can be: Why has it been diminished?
Here is why: The question is valid since it is on the same topic and a follow-up of the previous answer in the conversation. The question asks about the reason why the power held over Margaery by Cersei have diminished.

OK. solve this:
CONTEXT: IMO, it's simply due to the fact that film is a visual medium. Harry's disguise made every sense, and so he had it in the book (where you can stuff loads of details with minor explanations), but it was not overly important for the scene. Probably because of that, taking the time (and some special effects money) to show it and explain it was avoided. Also, having a different actor being Harry would be distracting for some of the viewers, even when explained, and it would also probably feel old (as in "we've seen this trick, why repeat it?"). So, unless there is a real need - from the perspective of the scene, not the plot - for Harry to be disguised, he's not.  <sep>  Q: Why did Harry not use Polyjuice Potion at the wedding of Bill and Fleur? A: Harry's disguise made every sense, and so he had it in the book (where you can stuff loads of details with minor explanations), but it was not overly important for the scene 
Answer:
Were there death eaters at the wedding?
