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

Q: In the Disney movie "The Hunchback of Notre Dame", Frollo takes for granted the gyspy woman that tries to save baby Quasimodo is his mom. But I've found a pair of details that actually point out that Quasimodo and the gyspy woman aren't related: 1. Quasimodo doesn't have the hair and skin color of a gyspy. 2. Neither she or the gyspy man with her call Quasimodo "son" (they may not be wife and husband!).  In the novel, Quasimodo's origin is unknown: He was left abandoned on the street, then he was found and adopted by Frollo because of compassion. Later in the novel, Frollo turns evil and insane because of his lust towards Esmeralda. Based on this, it is interesting to notice that Disney split the novel's Frollo into three characters: Frollo himself, the Arch Deacon and the gypsy woman, so it can be concluded that she adopted Quasimodo because of compassion.

A: In Disney's The Hunchback of Notre Dame: Is the gyspy woman really Quasimodo's mom?

Q: Maybe it's just me, but I was watching Top Secret for the first time today, and I realized that the scene where Nick (Val Kilmer) sings Tutti Frutti by Little Richard felt a lot similar to the scene in Back to The Future where Marty (Michael J. Fox) sings Johnny B. Goode by Chuck Berry.    In both movies, neither character was supposed to be singing Both songs were written by African Americans in the late 1950's Both songs were written in the future compared to the time the scenes were set in (the scene from Back to The Future was set in 1955, and as far as I can tell Top Secret was set during WWII) Both songs were clearly unexpected by both the listeners and the band Most of the listeners in both movies gradually liked the song more and more (except until the end in Back to The Future) Both movies had a lot of focus on a red electric guitar at the end of the song Possible similarity: In Back to The Future, Marty tells the band "this is a blues riff in 'B'," and in Top Secret, Nick also tells the band something, but I couldn't make out what he said.    My first thought was that since Top Secret is a parody film, that they got the idea from Back to The Future, but according to IMDB, Top Secret was released a year before Back to The Future.   So, my question is: did the makers of Back to The Future get the idea from Top Secret? Is it possible that the makers of Top Secret got the idea from Back to The Future before it was released? or are the similarities I see between to the two scenes merely coincidental?

A: Was the Johnny B. Goode scene from Back to The Future inspired from Top Secret?

Q: In Interstellar, after Cooper arrives in the Tesseract, Cooper tries to send the message STAY to his daughter in the past so she won't let him go on the mission. If that was his intention then why did he send the coordinates of NASA afterwards? If he didn't send the coordinates, he wouldn't have found NASA or go into space, he would have stayed.

A:
If Cooper wanted to stay, why did he send the NASA Coordinates?
