SUPERGIRL WEEK: 13 MEMORABLE TALES from Kara Zor-El’s earliest days… — Supergirl, starring Milly Alcock, is out, so we’ve gathered up the 13th Dimension crew to bring you our first-ever SUPERGIRL WEEK! Click here for more high-flying features! — By PETER BOSCH The new Supergirl movie has hit the big screenm and here at 13th Dimension, we’re celebrating it with a SUPERGIRL WEEK, something the Girl of Steel has deserved for a very long time. For my part, I quite happily volunteered to cover her earliest years, from landing on Earth to Superman revealing her existence to the world three years later.
