"Check out the place I went to!" she wrote on her blog. "They have made casts of everyone from Tom Cruise to Angelina Jolie for movies! It was so surreal seeing all these famous movie stars' faces on the wall!! Kind of scary, huh?"
Greenwald said making the mold was the first step in the process. That alone took several hours. Once they had a cast, they could play around with what look they wanted to create.
"It's like playing Mr. Potato head," she said.
Once the look was set, Mungle's team had to re-create it before the taping. "It's not like a Halloween mask," James said. "They were on set for at least four hours just getting into this look. Kim was on her computer while we making her up."
The end result made all the time spent worth it. And, with all the attention the show's been getting, Greenwald and James think there could be more in the future.
"It's a fun idea, one that I think a lot of celebrities will want to do," Greenwald said. "With this, they have the chance to be invisible."
