Andrew Kreisberg On What Makes Supergirl “Human For A Day”

“Human For A Day” is the title for the new episode of Supergirl airing Monday night, December 7 on CBS, and in it, Kara finds herself powerless, as we saw at the end of the previous week’s show.

What’s going on?

We spoke with Executive Producer Andrew Kreisberg on set last week for more details.

“It is something that is actually sort of new from the comics,” Kreisberg explained. “It was a Geoff Johns idea, which was that Superman or any Kryptonian’s cells are basically suffused with solar radiation an that’s where they get their powers from, and heat vision is an expulsion of that energy; that’s where it comes from, so you could just basically run out and you would need to recharge.”

“I was such a fan of that comic and that run,” Kreisberg continued, adding that he asked Geoff if they could do something with that plot point and that the DC Chief Creative Officer said “absolutely.” Kara is in a place now where she’s figuring out how to do things and when her powers are taken away, Kara really gets a chance to appreciate what it all means. “We also really like the idea, like Oliver [Queen] and like Barry [Allen], Kara’s a hero whether she has her powers or not. There’s this great moment in that comic book where Superman confronts that guy with a gun and basically talks him out of it… that became the centerpiece of that episode; you saw a little bit in the trailer,” he said.

“Basically, she emptied her powers killing the Red Tornado, and she needs a couple of days… unfortunately, it’s the day of the giant earthquake,” he teased.

You can see the trailer for “Human For A Day” below. For another recent Supergirl interview, check out our talk with Calista Flockhart at KSiteTV!
