‘Girl, Interrupted’ set had ‘intimidating’ Angelina Jolie vs. Winona Ryder ‘camps’ — who were the ‘cool girls’?

Girl, what?

The “Girl, Interrupted” set was “intimidating” for actor Elisabeth Moss — especially because there were Angelina Jolie vs. Winona Ryder “camps” while filming.

Appearing on the “Let’s Talk Off Camera With Kelly Ripa” podcast Wednesday, Moss, 41, opened up about her experience working on the 1999 drama when she was in her mid-teens.

“My mom was still with me going to set. We were shooting in Harrisburg, Pennsylvania. I was with all these movie stars. It was Winona Ryder! And Angelina Jolie!” recalled Moss.

“There were two camps. There was the Winona Ryder camp and the Angelina Jolie camp,” she went on. “I was so intimidated by the Angelina Jolie camp. I had no thoughts of ever being able to be in that camp. It was so cool. It was all the cool girls.”

The “Handmaid’s Tale” actress explained that the camps would divide “based on what was on camera,” and she ended up with Ryder, now 52.

The “Stranger Things” star and Jolie, 48, were in their mid-20s at the time, and for Moss, it was like “being dropped into ‘The Wizard of Oz.'”

Moss played Polly in “Girl, Interrupted,” a girl who was badly burned, and getting on the prosthetics took “about three hours every morning.”

“I would forget that I had [the prosthetics] on,” Moss told Ripa. “You wouldn’t take it off at lunch or anything. I would go with Winona, because we became kind of good friends, I would go with her to the store or something. People on set thought that that was actually what I looked like.”

In fact, it took time for some crew members to realize Moss wasn’t a burn victim.

“I wasn’t famous. Nobody knew who I was. So the crew actually thought, unfortunately, that had really happened to me,” she recalled. “It took a long time for them to realize it was not real. They did such a good job.”

Moss ran into Jolie years after filming wrapped. Although it was “incredibly intimidating” on set, she called Jolie “lovely” when she recently saw her.

“I never brought it up,” she joked of keeping the Jolie vs. Ryder camp theory to herself when she saw the Oscar winner. “I’m sure she would have no idea what I was talking about anyway.”

“Girl, Interrupted” also stars Clea DuVall, Jared Leto, Jeffrey Tambor, Whoopi Goldberg and the late Brittany Murphy.
