Gunn spoke about how this film informs 'Supergirl,' 'Lanterns,' 'Clayface,' and more. Without spoilers, of course.

All-Star Superman opens with the Man of Steel literally flying too close to the sun, as he rescues a group of astronauts and subsequently overloads his body with solar radiation. Even as he experiences newfound levels of strength, Kal-El finds his body is slowly dying, exploding one turbocharged cell at a time.

"What I wanted to do was mimic more what it was like to shoot jet fighters," says the writer/director of this summer's event film.
