'Supergirl' official teaser trailer: Watch Milly Alcock As Kara

Warner Bros. and DC Studios have finally unveiled the first trailer for Supergirl. 

Milly Alcock stars as a tougher, rougher Kara Zor-El with a drinking problem and zero interest in being her cousin’s polished copy. Her chaotic arrival was first teased in James Gunn’s Superman.

The new footage embraces a scrappy, colourful tone that fits right into Gunn’s offbeat universe, presenting a Supergirl shaped by her own demons and survival instincts. 

Supergirl hits cinemas on June 26, 2026
