Zack Sharf Digital News Director As thousands of moviegoers gear up for double features of Greta Gerwig’s “Barbie” and Christopher Nolan’s “Oppenheimer,” one person taking joy in the “Barbenheimer” craze is Nolan himself. Although his movie will be battling “Barbie” at the box office, Nolan recently told IGN that “it’s terrific” to have both summer tentpoles open on the same day. “Summer, in a healthy marketplace, is always crowded, and we’ve been doing this a long time,” Nolan said. “I think for those of us who care about movies, we’ve been really waiting to have a crowded marketplace again, and now it’s here and that’s terrific.” Cillian Murphy, who stars in the title role of “Oppenehimer,” agreed with Nolan, telling IGN: “I think it’s great. I mean, I’ll be going to see ‘Barbie.’ I can’t wait to see it. I think it’s just great for the industry and for audiences that we have two amazing films by amazing filmmakers coming out the same day. Could spend a whole day in the cinema, what’s better than that?”
