Given scene/plot descriptions from movies or TV shows, and given a specific question about the scene, summarize the question into a title

[Q]: Have the directors ever explained why the TV show Game of Thrones is named after the first book, instead of the book series "A Song of Ice and Fire"? However, it is based on the whole book series.
[A]: Why is the TV show titled "Game of Thrones" and not "A Song of Ice and Fire?"


[Q]: I have only watched a few episodes of Being Human (the original BBC series) so I may have missed something. (Just got hold of the dvds so trying to catch up.) In episode 3, George transforms into a werewolf after/during fighting Tully in the shed. He exhales a green mist just after the transformation has finished. I didn't notice this in any other episode, did it have something to do with fighting Tully? Eg, proximity of another werewolf?  Any other explanation - maybe just werewolves have very bad breath?
[A]: Why does the werewolf exhale a green mist?


[Q]: In Fantastic Beasts and Where to Find Them, Newt restrains Graves' movements with one of his friendly beasts and then proceeds to use the Revelio spell to... (spoiler)     reveal Graves' true identity, who is actually Gellert Grindelwald.   My question is, what gave him away? How did Newt realize that man was not really Graves? I was thinking maybe the speech he gave matched...    Grindelwald's ideas   ...and also the power and skill he displayed whilst fighting the aurors. Does anyone have a better explanation for this? Also, as a curiosity, what did...    Grindelwald   ...do with the real Graves? Maybe something similar to what was done to Alastor Moody in The Goblet of Fire?
[A]:
How did Newt Scamander realize "someone's" real identity?
