Bill Simmons has set the next documentary project from his Ringer Films at HBO, following on the success of 2018's Andre the Giant.

Simmons will executive produce Showbiz Kids, a feature-length doc about the highs and lows of children working in the entertainment industry, featuring interviews with some of the most famous former child actors in the world. Alex Winter, a fromer child actor turned director, will helm the project and also serve as an executive producer via his Trouper Productions, along with Glen Zipper of Zipper Bros (Netflix's Dogs).

The project will be the first at HBO since Simmons signed a new deal there in July.

"I have been fascinated by this specific topic for an especially long time, so grabbing the chance to explore it with people as talented as Alex and Glen was one of the all-time no-brainers for me and everyone else at Ringer Films," said Simmons. "There's a high degree of difficulty for this one, but I also think that's what makes it so appealing."

Added Winter (Bill & Ted's Excellent Adventure, The Panama Papers), "This project is very close to my heart, born of my own experiences in show business, beginning as a child on Broadway. 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."

Ringer Films is a division of Simmons' digital media company The Ringer (in which HBO is an initial investor). Showbiz Kids will be the second feature documentary from the company, following Andre the Giant, which debuted in April 2018.

Winter, Zipper and Ringer Films are repped by CAA. CAA Media Finance brokered the deal with HBO on behalf of the filmmakers.
