There will probably be a lot of nods to Black Douglas, Beowulf, Sir Gawain and The Green Knight.
Guessing it will all soup down into one spectacular failure - it's been done before. People are tired of Star Wars now, just as Lucas feared.
The next implosion will be MCU and the Infinity Wars, you wait and see. The trailer is muck. There'll be a rush order on a Panther 2 and WW2 but a whole lotta behind-the-scenes cancels on the Thor/Cap/Spidey series.
Thor and Captain America already got 3 movies. Iron Man only had 3, and he was more popular, so they are probably done with those series anyway.
Spider-man will definitely get 2 more movies. The first was a hit, and he’s more bankable than Iron Man for sure. There’s going to be a Guardians 3 for sure as well, and Ant-Man 2 is already ready to drop.
