What is Young Sheldon?
Young Sheldon is an upcoming spin-off series from The Big Bang Theory which will focus on the life of the nine-year-old Sheldon Cooper growing up in East Texas and going to high school. As established on The Big Bang Theory, Sheldon Cooper was a boy genius who grew up in a religious Texan home.
Iain Armitage (Big Little Lies) will star as the nine-year-old Sheldon Cooper. Zoe Perry, the real-life daughter of Laurie Metcalf who plays Sheldon's mother on The Big Bang Theory, will star as Mary Cooper. Other cast members include Lance Barber, who will play Sheldon's father George, Raegan Revord, who will play Sheldon's twin sister Missy, and Montana Jordan, who will play Sheldon's older brother, George Jr.
Young Sheldon will be a single-camera comedy (eg. The Wonder Years, Malcolm in the Middle), rather than the mutli-camera style of The Big Bang Theory which is filmed in front of a studio audience. The show will be narrated by Jim Parsons as Adult Sheldon. Jon Favreau (Iron Man, Elf) is signed on to direct the pilot episode.
Young Sheldon was created by The Big Bang Theory co-creator and executive producer Chuck Lorre and EP and show-runner Steven Molaro. Chuck Lorre, Steven Molaro, Jim Parsons and Todd Spiewak will serve as executive producers on the show, from Chuck Lorre Productions, Inc. in association with Warner Bros. Television.
When will Young Sheldon air?
CBS has placed a series order for Young Sheldon for the 2017/18 season, which runs from September 2017 - May 2018. CBS has not yet confirmed scheduling plans, but CBS CEO Les Moonves has suggested Young Sheldon is likely to air immediately after The Big Bang Theory. This would point to Young Sheldon also being part of CBS's line-up starting in Fall 2017, rather than as a mid-season replacement.
Does this affect The Big Bang Theory's future?
No, Young Sheldon was announced just before The Big Bang Theory was renewed for a further two seasons by CBS, taking the show through to its twelfth season in 2018/19, so the spin-off does not mean an end for the show.
