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:`.

Question: 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?


Question: CONTEXT: He's clearly gesturing for them to take cover Essentially, the waving of the arms is meant to imply "get down"...out of harms way from the attack that is forthcoming. I suspect that this is intended to show that the attack was aimed at military targets and that even Japanese airmen/military weren't above showing some humanity.  <sep>  Q: What's this Japanese bomber machine gunner gesturing with his arms? A: He's clearly gesturing for them to take cover 

Answer: Are you speaking about the gesturing at the 1:27 mark?


Question: CONTEXT: Firstly, there's a chance Wednesday would sense them coming, and would get away. They couldn't have a decent conversation then, and Mr. World made it very clear they wanted to part on respectful terms, having made their proposal. However, in the room Wednesday and Shadow were kept, Media, World, and Technical Boy were able to enter unobstructed, through the only exit, so it was very much their ground. Secondly, it was a show of power. Wednesday is on the wrong side of the law (after the robbery), but the new gods aren't - or at least, they're useful to the law, with the satellites and all the like. They wanted to show Wednesday that they had the capability to track him if the wanted, and that he had something, namely the whole of law enforcement, to be aware of. Thirdly, I think it's the matter of not getting their hands dirty. Gods, both in the novel and in the series so far, operate through proxies - Wednesday has Shadow, Technical Boy had those dumb henchmen. It's possible (though unlikely) that the New Gods don't want to be on the wrong side of law enforcement as well, and the law enforcement was looking for the bank robber anyway. In this case Mr. World simply used the policy in place of his own men, but disposed of them as they became unnecessary (which could be seen as yet another show of power).  <sep>  Q: Why did Mr.World need to involve the police? A: They couldn't have a decent conversation then, and Mr. World made it very clear they wanted to part on respectful terms, having made their proposal  Q: Why did Mr World have to be so violent? A: Mr. World simply used the policy in place of his own men, but disposed of them as they became unnecessary (which could be seen as yet another show of power  Q: Why not just go to the motel room? A: They wanted to show Wednesday that they had the capability to track him if the wanted, and that he had something, namely the whole of law enforcement
