Gunn on his new Supergirl:
“This is a very different type of Supergirl. In our [film], we see the difference between Superman, who was sent to Earth and raised by loving parents from, you know, the time he’s an infant, versus Supergirl, who was raised on a rock chip-off of Krypton and watched everyone around her die and be killed in terrible ways for the first 14 years of her life, and then came to Earth when she was a young girl and is much more hardcore. She’s not exactly the Supergirl we’re used to seeing.”
Alock’s recent credits include:
- Upright
- House of the Dragon
- Furlough
- The Familiars
- Reckoning
Synopsis for the graphic novel:
Kara Zor-El can no longer find any meaning or purpose in her life. But all that changes when an alien girl seeks her out to help her take revenge on the bad guys who destroyed her world. Now a Kryptonian, a dog, and an angry, heartbroken child head into space on a journey that will shake them to their very core. It’s Supergirl like you’ve never seen her before in a character-defining sci-fi/fantasy masterpiece!
