Renée Zellweger Transformed Into Pam Hupp for ‘The Thing About Pam’

Similar to our reactions, showrunner Jenny Klein was shocked by Renée’s uncanny transformation. “Seeing Renée as Pam for the first time was totally surreal. I had studied so many hours of Pam, the real person, on police surveillance videos, and then here she was walking onstage in front of me,” she stated.

“And it wasn’t just the physical transformation. It was the way Pam carries herself, her dropped foot, her mannerisms, her sniffs, and even the way she often talks with her hands. It was completely mind-blowing because I didn’t see Renée. I saw Pam. And that was also a little bit scary.”
