"The Big Bang Theory" is well under its tenth season, but it seems that fans have not tired of it yet. In fact, rankings for the show kept steady, and it seems that fans still want more, so CBS is giving it to them. "Young Sheldon," the prequel series about the show's weird nerd will soon find its way to the small screen.

Hollywood Reporter said that Lance Barber, Raegan Revord and Montana Jordan joined the cast of the new comedy, which will be helmed by "The Big Bang Theory" showrunner Chuck Lorre, and Steve Molaro. Jim Parsons also signed on, albeit as a narrator for the series.

Lorre and Molaro already started casting ahead of the pilot's production, which will start later this month. This is the first time that the network and producers confirmed the spinoff project, but there had been no confirmation regarding the number of episodes for the new show.

"Young Sheldon" will revolve around one of the central characters from  "The Big Bang Theory". Sheldon Cooper, a nine-year-old boy genius from East Texas who struggles with his life as a high schooler at such a young age. "Big Little Lies" actor Iain Armitage will be playing the role of the young Sheldon Cooper (played by Parsons in the original series). "Modern Family" actress Raegan Revord was also cast in an undisclosed role, although she is rumored to play Sheldon's twin sister, Missy.

No premiere date was set for the series yet, but CBS News did note that "The Jungle Book" director Jon Favreau signed on to helm and executive produce the pilot episode. Numerous references were made regarding Sheldon's childhood in the long-running CBS comedy, which gives the writers a lot of material to work with for the spin off. "The Big Bang Theory" is still in the middle of contract re-negotiations for at least two more seasons, ensuring that there will be more to see of TV's most lovable nerds.
