It was the one that starts with Claw (Andy Serkis) & Ross (Martin Freeman) in an interrogation room, and I yelled "He's got a ring in his pocket!" My mother (I took her to see Thor 3) did that thing where she tries to remonstrate with me while suppressing laughter through her nose.
This is sort of my new fun mental exercise - describing movie plots, only substituting other sci-fi/fantasy/superhero characters the actors have played. So Black Panther is really about Bilbo Baggins questioning Gollum about a country ruled by Jackie Robinson, who has Michonne & Maz Canata as bodyguards, and Johnny Storm for an arch-nemesis. I am assuming. Justice League is about Daredevil & Giselle recruiting Khal Drogo and some other guys with the help of Simon Gruber, to honor Duke Charles Brandon's memory.
The ease of this game probably says something rather creepy about the state of popular entertainment.
You want to see Luke Skywalker go to the Wizarding school of Hogwarts and get taught by Gandalf. Of course his nemesis would have to be Egwene.
