HBO will shine a spotlight on children in show business, unveiling Tuesday the feature documentary Showbiz Kids. The film, to be directed a former child actor-turned-director Alex Winter, will be executive produced by The Ringer Films’ Bill Simmons, Trouper Productions’ Winter and Zipper Bros’ Glen Zipper.

The pic will follow the highs and lows of children in show business, featuring interviews and examinations of the lives and careers of some of the most famous former child actors in the world. A 2020 release is being eyed.

“This project is very close to my heart, born of my own experiences in show business, beginning as a child on Broadway,” said Winter, who started his career onstage in The King & I and Peter Pan before eventually achieved cult status co-starring with Keanu Reeves in the Bill & Ted franchise. “Glen Zipper and I are thrilled to be collaborating with Bill Simmons and HBO. I’m a huge fan of Bill’s great work in the doc space and HBO is the perfect platform for an incisive pop culture saga.”

Winter recently released The Panama Papers for Epix, in addition to the docu Trust Machine: The Story of Blockchain for SingularDTV and Futurism Studios. Zipper and his Zipper Bros Films previously worked with Winter on Panama Papers as well as the upcoming Zappa. Zipper also has a first-look TV deal at Bad Robot.

Simmons’ Ringer Films has a deal at HBO; they previously teamed on the feature docu Andre the Giant.

Winter, Zipper and Ringer Films are repped by CAA
