In Tim Burton's Batman Returns, Max Shreck throws Selena out a high story window where she plunges to the ground. It's not quite clear to me if she dies upon landing or just knocking at death's door.
Regardless, cats come out of nowhere and start licking her and nipping at her fingers:
Next thing you know, she's more assertive, confident and has quite the spring in her step (the back-flips and whatnot).
What role did the cats play making Catwoman?
