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

[Q]: During Avengers: Infinity War Thanos killed Vision to take the Mind Stone from his head.  During Avengers: Endgame Tony Stark (Iron Man) tells Professor Hulk to bring everyone back as they were 5 years ago, which he does by performing "the snap".  Does this mean that this character was brought back? If so, where was he during the final battle?
[A]: Is this character still alive after the events of "Avengers: Endgame"?


[Q]: As anyone who has seen the movie will tell you, the Eraserhead baby is the stuff of nightmares.     The baby itself is famous for being somewhat of a mystery. David lynch refuses to discus the baby, what it is, how it was created, or why it's so gosh darn creepy. The few comments he has made have been cryptic. Statements such as "it was born nearby" or "maybe it was found" have lead to rampant speculation including theories that it could possibly be such things as a skinned rabbit or a cow, lamb, or even human fetus.  The prop itself, nicknamed "Spike", featured several working parts making its eyes, mouth, and ears capable of independent operation.  What is the baby actually made of and what evidence do we have to prove this?
[A]: What is the Eraserhead baby?


[Q]: Why are movie closing credits usually animated by scrolling them from the bottom to the top of the screen? Is this because in old times there was no computer animation and the credits text template was scrolled-up mechanically by a man/device? Nowadays there must be thousands of possible ways for credit frame transitions, but still the old one is preferred.
[A]:
Why do movie credits scroll from the bottom to the top of the screen?
