The Big Bang Theory star Jim Parsons will be on two TV shows this fall. CBS created a spin-off series about his brainiac character growing up in East Texas at age nine. Young Sheldon stars newcomer Iain Armitage with Parsons cast as the narrator. Parsons told Entertainment Tonight, (quote) “We saw lots of auditions. There's something about Iain that just popped immediately. There's no denying it as soon as you saw his face and he handles the [scientific] language.” Yesterday, CBS released a five-minute preview of Young Sheldon, which will follow The Big Bang Theory. Check it out below… what do you think? A lot of critics say it’s not as good as they were expecting!
