Since Superman was released in cinemas a couple of weeks ago, DC fans have been dying to know who is who in the mysterious mural that can be seen in Metropolis' Hall of Justice in the movie. Last week, James Gunn finally unveiled a first full look at the mural, which features 26 iconic superheroes from the comics.

During his first public appearance following his latest box office hit, the filmmaker earned a standing ovation from the Hall H crowd while choking up as he talked about his love of the comic book medium.

First Steps and Superman share some surprising similarities that allow both to stand out from the more mediocre superhero movies of late.
