“Smart Hulk was in the third act of
Infinity War,” Markus revealed. “We wrote it, we shot it, and went on to shoot most of Endgame, and he achieved union with the Hulk while inside the Hulkbuster. He kicked Cull Obsidian’s ass. But it didn’t work. It was the wrong tone for the movie. But we had already shot Endgame, where he was already Smart Hulk.”
“A big sequence where you see the union takes away from the attention of the story. A scene where Hulk eats a stack of pancakes [...] I’ve never seen that in a movie,” Markus said.
