An A-lister makes an appearance in the new "Superman" movie, in reference to the hero's origin story.

Rather than give an origin story to the iconic DC hero, Gunn’s film picks up in a world that is well familiar with Superman and has several other heroes flying around as the Justice Gang, an early prototype of what’s soon to become the Justice League.

The David Corenswet-led film is both a reboot and the big-screen introduction to a new DC Universe that will unfold in the coming years across movies and television. While Superman isn’t technically the first official new DCU project —that honor belongs to last winter’s Creature Commandos—the new film is Gunn’s first broad-stroke,

Now that Superman is finally back in theaters, it’s time to revisit his old adventures.

Instead of retreading narrative subject matter audiences have become bored with (no baby Kal-El in a spaceship crashing to Earth here), Gunn's take on the character's story drops the audience into an already built world.
