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

[EX Q]: In this scene in Hot Fuzz (2007) the camera focuses on these two characters and rotates slowly, but the background rotates so fast. So what is this camera effect and how is it accomplished? Timeline of this effect in the movie is around 97:46.
[EX A]: What is this camera effect used in Hot Fuzz?

[EX Q]: The first season of House of Cards starts with the inauguration of Garrett Walker as 45th President. If the show is true to reality, that would make Walker the successor of Barack Obama, and have him inaugurated in 2017. Is there any in-show evidence that the first season of House of Cards really does take place in 2017? Or, alternately, that the show follows some sort of alternate history, like The West Wing did? If the latter, do we know the differences?
[EX A]: In what year is House of Cards set?

[EX Q]: In the movie Predator (1987), near the climax, when the Predator finds Arnold, it did not try to kill him immediately. Instead, it goes near him and checks his head and removes its helmet (I am assuming that it would be its helmet). Why did it not kill Arnold immediately as it killed everybody else? Did checking Arnold's head mean something?
[EX A]:
Why did the Predator not kill Arnold immediately as it killed everybody else?
