Star of new 'Inside Out' series 'Dream Productions' on Pixar's first TV show

The world of Inside Out expands in the new series Dream Productions.

Taking place between Inside Out and Inside Out 2, Dream Productions follows the studio inside Riley's head that creates the dreams she has every night. It's Pixar's first TV show and will be available on Disney+ on Wednesday.

Paula Pell stars as acclaimed director Paula Persimmon, and while she had small roles in the Inside Out films, she told ABC Audio how special it is to be a part of the Pixar family in this way.

"I was thrilled to be the small parts I was in the big movies," Pell said. "To have my character specifically spin off into this story was so moving to me and touching and exhilarating."

Pell said she actually didn't believe Pixar when they approached her about the show, but after learning the story she understood why.

"They know how to tell a great story," Pell said. "There's nothing better than Pixar. They just do it in a way where everyone goes, 'Oh my God.' They walk out of Pixar movies like, 'Well, that's the gold standard right there.'"

Paula Persimmon faces a nightmare of her own throughout the show. Riley's growing up, and that means her dreams need to grow up, too. Pell said she could relate to her character in more than just having the same first name.

"I just turned 61 ... I spent so many years being younger and doing comedy and writing and all that. And then as I aged, I started feeling that, in my 40s and 50s and then in my 60s, the fear of becoming insignificant," Pell said.

It's a fear Paula Persimmon shares.

"It is a wonderful lesson that you can keep invigorating yourself and become as fresh as a daisy with your new thoughts and your new ideas, because that never goes away," Pell said. "The only way it'll go away is if you sabotage your own self."
