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

Ex Input:
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 Output:
Why did the Predator not kill Arnold immediately as it killed everybody else?

Ex Input:
This is something very common, that we all have been seeing since as long as we can remember. This question stemmed from my recent re-watching of Django Unchained, where Quentin Tarantino makes a cameo appearnce. I have always been intrigued by this. M Night Shyamalan, Peter Jackson, John Carpenter, Robert Rodriguez, Eli Roth, and many more, have made frequent cameo appearnces in their movies. The trend goes as back as Alferd Hitchcock's movies. I want to know more about this. What are the factros behind this gesture ?

Ex Output:
Why do directors make cameo appearances in their movies?

Ex Input:
In the movie Spider-Man: Into the Spider-Verse, after being bitten by the radioactive spider, Miles go back to his graffiti to check the dead spider again. At this point the spider is shown glitching before Miles discover the secret laboratory. So does this mean the radioactive spider is from a different dimension? Since only different spider-people are sucked out of their dimension, does this mean in this spider's dimension, it hasn't yet bitten it's spider-person?

Ex Output:
Which dimension did the radioactive spider which bit Miles come from?
