Netflix, a leading Internet TV network, announced Thursday that actress Julie Andrews will star in Julie’s Greenroom, a new preschool show from The Jim Henson Company that features an all-new puppet cast of kids learning about the performing arts. The series will be available exclusively to Netflix members globally in early 2017.

Andrews, who created the series with her daughter Emma Walton Hamilton and Judy Rothman-Rofė, will executive produce and star as Ms. Julie – the director of the Wellspring Center for the Performing Arts in which she teaches performing arts workshops in the theatre and its “Greenroom.”

Ms. Julie and her devoted assistant Gus (Giullian Yao Gioiello) bring the performing arts to a new generation of kids known as the “Greenies,” played by original puppet characters built by Jim Henson’s Creature Shop.

The Greenies are a diverse group of kids who are mesmerized by all that the arts and creativity has to offer. Over the course of the season, with Ms. Julie’s guidance and inspiration from the visiting guest artists, the kids create an entirely original new show, that is a mashup of all the performing arts including mime, music, dance, improv, circus arts, voice and more.
