Superman succeeded in establishing a vast, detailed world with a rich history that surrounds aliens and metahumans. It even introduced several iconic comic book characters with roots far beyond Superman’s, including the Green Lantern, Hawkgirl, Mr. Terrific, Metamorpho, and the Engineer. This was all done on planet Earth.

Supergirl is a way more rock & roll film. It’s a little bit rougher, in certain ways. She’s a tougher character. She’s not Superman at all. And so it’s not the same. This movie really is for everybody.
