David Corenswet, who plays Superman in the new DC Universe, quickly came to the defense of his co-star Milly Alcock during the premiere of 'Supergirl' in New York City on Monday night.
A photographer reached out and touched Alcock's back, prompting Corenswet to intervene.
Video shows the actor moving through the crowd and signaling the photographer to keep a respectful distance.
The incident has gone viral, with fans applauding Corenswet's protective gesture. Many noted the real-life parallel to his on-screen role as Clark Kent.
Alcock, who stars as Supergirl, is set to showcase her own heroics when the film hits theaters on June 26.
