Internet TV giant Netflix has teamed up with The Jim Henson Company to produce Julie’s Greenroom, a new 13 x half-hour preschool show co-created by and starring Oscar winner Julie Andrews and a cast of original puppet kids.

Set to launch exclusively to Netflix members globally in early 2017, the Netflix Original series follows Andrews as Ms. Julie, the director of the Wellspring Center for the Performing Arts, and Giullian Yao Gioiello (Catfight, The Carrie Diaries) as her loyal assistant Gus as they teach performing arts and theater to a diverse group of kids known as the Greenies.

Over the course of a season, the Greenies use what they learn to create an original show for the Center, blending performing arts elements such as music, dance, mime, improvisation, circus arts and voice work.

Andrews co-created the series with her daughter and longtime co-author Emma Walton Hamilton (The Very Fairy Princess) and TV writer/producer Judy Rothman-Rofė (Jim Henson’s Word Party, Angelina Ballerina: The Next Steps).

Both Andrews and Walton Hamilton are executive producing the series along with Steve Sauer, and Lisa Henson and Halle Stanford from The Jim Henson Company.

Serving as co-producer and director is Emmy-winning actor and writer Joey Mazzarino (former head writer of Sesame Street), while fellow Emmy winner Bill Sherman (Sesame Street) is the series’ composer.

While nearly every episode will have an original song, all eps will feature a guest star to help the kids with their studies. Visiting artists include Alec Baldwin, Sara Bareilles, Joshua Bell, Tituss Burgess, Carol Burnett, Chris Colfer, Robert Fairchild, Josh Groban, David Hyde Pierce, Bill Erwin, Ellie Kemper, Idina Menzel, Tiler Peck and Stomp.

Production on Julie’s Greenroom began this month in Long Island, New York.
