What the teaser shows
The image is grainy and shows pale markings on a dark surface. It appears to contain chalk-like writing or drawings, but the resolution makes details hard to confirm.
Cast comments from set
Cast members who are filming Avengers: Doomsday have made public comments about their experiences on set, while avoiding plot specifics.
Speaking to Collider, Channing Tatum said: “You just can’t understand what this is going to be,” Tatum said. “Anybody that has loved these things growing up, it’s going to melt your brain. It’s going to be the biggest thing that they’ve ever done, that is for sure.”
David Harbour spoke to ScreenRant and said: “I will say I’ve never been on a set like this in my life. I’ve never seen anything like this. You saw those chairs. So it’s like, every one of those guys and girls has a trailer. It’s just insane to look around the room and be like, ‘Oh my god, I’m in the movie. There’s what’s his face doing that speech.’ It’s just enormous.”
