While filming in London, Alcock was photographed standing atop a tank in her Supergirl suit, which appears to be comic-accurate with its red skirt and boots. A short cape can be seen on her back—a minor departure from the original design, which features a much longer cape.

The film follows Kara Zor-El as she begins traveling the galaxy with her dog, Krypto, on her 21st birthday. Along the way, she meets a young girl named Ruthye and joins her on a bloody revenge quest.
