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]: This is very confusing, why would the Disease Department in The Maze Runner unleash a deadly and painful virus when there could have possibly been other ways to control the human population? like executing criminals and stuff like that? and why did the combined governments agree to it when they know that they are risking wiping every trace of human life out of existence?
[EX A]: Why would the Disease Department unleash a disease when there could have been other ways to control the population?

[EX Q]: During the course of the Avengers, you see Mr Banner talk about his alter ego as just another entity inside of himself. Afraid, reluctant and very much un-willing to let him out, even if it means his escape from being captured by S.H.I.E.L.D. Citing Hulk's violence, lack of self-control, and raw power that would come of unleashing such a creature.  However, during the argument on the plane as well as for the final battle, Banner is willing, and eventually does let the beast lose, seemingly without knowledge as to whether or not he can control him properly.  Why does Banner choose to release the Hulk and where does he get the confidence he needs to be sure that he can point the indestructible beast towards the enemy, and not towards the Avengers?
[EX A]: Why does Banner finally allow the Hulk to come out?

[EX Q]: While looking for various actors and actresses I keep coming across material they have done that isn't on their IMDB profile.   An example is Allison Scagliotti is in a web short yet there is no mention of it on her page, the web short did give her credit but this isn't always the case. I've noticed that music videos and web videos don't normally show up on IMDB as well as sometimes older roles that the actor/actress doesn't acknowledge.   Since IMDB is generally the go to for if an actor/actresses was in something. If it's not listed on IMDB or their wiki page (and in some cases I've come across not the actor/actresses own personal page) then how can I make sure if the actor/actress is the one I believe they are?
