The Big Bang Theory: Spin-off series about young Sheldon

While the spin-off is only in early stages of development it is expected that the show will be a prequel set in the 1990s. The new show will centre on the young, neurotic genius, Sheldon as he grows up in Galveston, Texas with his more average family.

Sheldon Cooper will be joined by characters from the original series, such as his fraternal (and completely unlike) twin sister Missy. His older brother George (before only mentioned) may also make an appearance. For now it is unknown if Laurie Metcalf, who played Sheldon’s Evangelical Christian mother Mary recurring in the main show, will also reprise the role in the spin-off.

The Big Bang Theory, famous for its scientific humour, puns and one-liners, is one of the top comedy shows on TV with an average of 18 million viewers every episode. The current tenth season of the series is the last in the three-year contract with the CBS who are expected to start discussions about renewing the contract for another 2-3 seasons with the Big Bang Theory crew.

The Sheldon spin-off would give the BBT fans an insight into his often referenced childhood. Although the pilot is yet to be written, the show is hoped to be a new comedy TV success. Jim Parsons, playing the lovable nerd in the original show, is expected to be a part of the executive production team, along with Chuck Lorre and Steve Molaro. Big Bang Theory co-creator Bill Prady is also expected to be one of the executive producers.
