James Gunn Reflects on David Corenswet & Rachel Brosnahan’s Superman Screen Test

Superman writer/director James Gunn has reflected on the screen test between David Corenswet and Rachel Brosnahan exactly one year after it occurred.

In a post on Threads , Gunn — who is also co-CEO of DC Studios — offered new insight into Corenswet and Brosnahan’s screen test, as well as what it has been like to work with them on the highly-anticipated DC Unive r se movie.

“One year ago today David and Rachel screen-tested for Clark and Lois. When they first read together it was like magic,” Gunn wrote in the social media post. “What a wonderful year it’s been with two of the most extraordinary, vibrant, and meticulous actors I’ve ever had the opportunity to work with. I can’t wait for you to see them on screen in just a little over a year.”
