OK, so let me grab to "random" books then that are movie hyped.
Incredible Hulk #271 9.8 - 1st Rocket Raccoon
2011 (high) - $64
2012 (movie announced) - $350
2014 (movie release) - $1,250
2018 (high) - $575
Iron Man #55 9.8
2011 (high) - $1,800
2012 (movie announced) - $3,219
2014 (movie release) - $5,155
2018 (high) - $8,300
So, what these two instances show is that while there was movie "hype", the characters have sustained themselves in the pop culture world. At least for now. You are comparing prices stating that a movie hype" book should be worth 10% of what it was worth prior to a movie.
