When talking about her first day on the ser of 'Supergirl', Milly Alcock confirmed that Superman will be in the film, something fans hoped for but did not know for certain.

Milly Alcock: It was with Superman. And I wasn't in the suit, and I was speaking a different language. That day was really hard. It was like two degrees. That was a hard day. The whole scene was in Kryptonian.

2) 'Supergirl' Shows Young Women It Is Okay To Be Flawed

Supergirl is not Superman, in that she is a very flawed individual. Both Milly Alcock and James Gunn agree that 'Supergirl' is about showing young women that this is perfectly okay.

Milly Alock: I think that what Supergirl represents for young women especially is that you can be flawed and that you can be openly, you don't have to be perfect in order to come to some internal self-resolution. I think that we're thrusted upon this narrative, especially women, that you have to be perfect in every aspect of your life. And I think that Kara is someone who so beautifully leans into her flaws. And I think that that's really special.
James Gunn: Yeah, I agree with you. That's really what spoke to me both in the book and on the script is that a lot of times for some reason our female superhero leads are just so much more perfect than our male. Tony Stark and Star-Lord are such messes. And yet that isn't always the same thing for our female superhero leads and seeing somebody who was just so imperfect and such a mess but just really a beautiful soul.

3) Craig Gillespie Explains That The Fight Sequence Camera Work Changes A Lot During 'Supergirl'

As discussed earlier, Kara Zor-El is a bit of a mess, and because of that, depending on what mood she is in and where they are in the story, the fight sequence camera work in 'Supergirl' changes.

Craig Gillespie: There was a lot going on, but it was really exciting in a way because in each case, it was always a little different. It's like whether she had her full power, whether she had no power if she's on a red planet, whether she has the fully generated power, and also emotionally where she is in the story dictated a lot of how these fight sequences go. So if she's in a very angry place, it's going to be a much more phonetically camera, like messy, kind of aggressive camera work. If she's feeling in the zone, so to speak, the camera work gets more fluid. So trying to figure out where we are in the story and how that reinforces her emotionally with the fight sequences was really fun.

4) The Majority Of 'Supergirl' Takes Place In Space

'Superman' and 'Supergirl' are very different films. They are both a very different tone, and 'Supergirl' takes place almost entirely in space, Craig Gillespie explains.

Craig Gillespie: They are so different in tone. And to be able to really lean into it and embrace it, and plus, are we allowed to say this? It's like the whole movie takes place in outer space. So it's a very different world to start with. We had a completely blank slate.
James Gunn: The outer space thing's a big part of it. Because it is a space fantasy.

5) Krypto Is A Big Part Of 'Supergirl'... And He Is Still Not A Good Boy

As seen in the teaser trailer, Krypto is going to be a big part of 'Supergirl', and to no one's surprise, he is still not a good dog.

James Gunn: I think you'll see pretty quickly he's returning. I don't think he knows what good is. I think he just exists in his own head space. He's not a good dog. He's a terrible dog. He continues to be a terrible dog. The difference is Kara loves him as a terrible dog. She loves him. Whereas he gets on Clark's nerves, you know? Maybe he'll get better.

What is the plot of 'Supergirl'?

While celebrating her 21st birthday, Kara Zor-El travels across the galaxy with her dog Krypto, during which she meets the young Ruthye Marye Knoll and goes on a "murderous quest for revenge".
