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

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

Example Input: I clearly don't understand the motivation for President snow of the Hunger Games: Mockingjay and the leader of the Capitol (Capital) to hurt Katniss Everdeen by using Peeta on screen and getting Peeta to say all these things about a ceasefire but when the rescue team from District 13 go to the Capitol and rescue some remaining tributes from the Hunger Games that have been held ransom, they are helped out by some supporters in the Capital itself. But when they get Peeta back to 13, he attacks Katnis by strangling her.  Why would President Snow just let Peeta be captured by District 13 rescuers and let 13 take him? Also to add: why would Peeta have saved 13 from the bombing from the Capital and basically saves them, when he is rescued he attacks her? what is going on here?
Example Output: Why did President Snow want to use Peeta to kill Katniss?
