CBS has announced a series order for a spin-off of The Big Bang Theory following the early life of Sheldon Cooper, titled Young Sheldon, to air during the 2017/18 season.

Young Sheldon will follow the nine-year-old Sheldon Cooper, played by Iain Armitage (Big Little Lies), living with this family in Texas and going to high school. Zoe Perry, the real-life daughter of Laurie Metcalf who plays Sheldon's mother Mary on The Big Bang Theory, will be playing Sheldon's mother in the spin-off series. The show will also star Lance Barber, Raegan Revord and Montana Jordan.

Young Sheldon will be a half-hour series but, unlike the multi-camera The Big Bang Theory, the show will be a single-camera comedy. Jim Parsons will narrate the show as Adult Sheldon. Elf and Iron Man director Jon Favreau will direct the pilot episode.

Young Sheldon was created by The Big Bang Theory co-creator and executive producer Chuck Lorre and executive producer and show-runner Steven Molaro. Chuck Lorre, Steven Molaro, Jim Parsons and Todd Spiewak will be executive producers on the show which will be produced by Chuck Lorre Productions, Inc. in association with Warner Bros. Television.

The Big Bang Theory has not yet been renewed renewed past its current tenth season, but new contracts for the cast are reportedly close to being signed and a two-year renewal deal is expected according to press reports.
