Young Sheldon is one of CBS鈥檚 new fall TV shows, and let us tell you 鈥 fans of The Big Bang Theory might really dig it. It鈥檚 a lot of fun and has a lot of heart.

If you鈥檙e not sure about Young Sheldon, here are a few tidbits to whet your appetite, from the cast and creators at the 2017 TCA summer press tour on Tuesday.

1. The Wonder Years was a big influence. Lorre admits that he鈥檚 鈥渁 nervous wreck鈥 to make a single-camera comedy with narrative voice-over, which is something he鈥檚 never done before, but he鈥檚 also excited to try something new and has definitely drawn inspiration from shows like The Wonder Years.

鈥淲e absolutely discussed Wonder Years when we were writing. I鈥檝e never worked with narration before. Narration changes the way you write. We looked at shows that used narration and Wonder Years did it beautifully. Nobody did it better than The Wonder Years,鈥 Lorre says.

2. This idea has been brewing for years. 鈥淲e鈥檝e been interested in writing about the origins of Sheldon for a few hundred episodes now,鈥 Lorre says. Co-creator Steve Molaro adds, 鈥淭here鈥檚 a bit of a joy of discovery about Sheldon at nine that we鈥檝e been having a lot of fun with.鈥

3. There鈥檚 a wealth of TBBT things that could pop up on Young Sheldon. The creators say that the show could touch on things that Big Bang Theory fans have heard about. 鈥淲e know he tried to get uranium to build his own nuclear reactor to give the town free electricity,鈥 says Molaro. 鈥淲e know he had his sister push him around in an office chair with a Speak 鈥榥鈥 Spell around his neck so he could be Stephen Hawking, but everybody just thought he was R2D2. Those are a couple I find amusing.鈥

4. But the show could affect TBBT鈥榮 future, as well. On the flip side of fans getting to see things they鈥檝e only heard about on The Big Bang Theory is the idea that things that happen on Young Sheldon could impact present-day Sheldon. 鈥淲e discussed the possibility [that] the stories we鈥檙e telling on Young Sheldon can echo into The Big Bang Theory. People can come into his life in 1989 and impact him and they might be on The Big Bang Theory 20, sorry, 30 years later. So we鈥檙e definitely discussing the ripple effect the show can have going forward in time,鈥 says Lorre.

5. Sheldon won鈥檛 be the only focus. The show is about Sheldon as a kid, but鈥檚 also about how hard it is on his family to be coping with a nine-year-old who is in high school with his older brother. 鈥淎 big part of the fun of the series is to not just watch Sheldon develop, but how his family adapts. 鈥 Their lives have to change in order to accommodate him,鈥 says Molaro. 鈥淎ny time that you have a kid that isn鈥檛 exactly typical, it can be difficult for the child and it can be difficult for their siblings and for the parents. 鈥 I think this is an opportunity for this show to explore the highs and lows of that and how it impacts everybody.鈥

6. There鈥檚 more to Sheldon鈥檚 dad than TBBT let on. Sheldon has never spoken very highly of his father on The Big Bang Theory, but Young Sheldon鈥榮 creators say there鈥檚 鈥渕ore to his dad than we were led to know.鈥 They also add that the show doesn鈥檛 have to follow 鈥渁n exact timeline鈥 where a year on the show is a year in Sheldon鈥檚 life, so Sheldon鈥檚 father鈥檚 death when he is 14 years old isn鈥檛 necessarily a tent pole moment coming up in season five, should they be on the air that long.

7. Get ready for young Mary Cooper. If you haven鈥檛 heard, the show cast Laurie Metcalf鈥檚 real-life daughter, Zoe Perry, as young Mary Cooper, Sheldon鈥檚 mom 鈥 and her performance is uncanny, which Perry tells Brit + Co she can鈥檛 really take credit for. It鈥檚 thanks to genetics that she sounds and looks so much like her mother. But Perry did go back to study her mom on The Big Bang Theory before her audition.

鈥淲hen I first got the audition, I rewatched all the episodes that she was in. I just wanted to be sure I was in the same ballpark as her,鈥 Perry explains. 鈥淚 think what鈥檚 so wonderful and a privilege to play Mary Cooper at this age is we don鈥檛 know her at that stage of her life yet, so I think it provides me a little bit of flexibility.鈥

Lorre says being able to cast Perry was an incredible piece of good fortune for the show. 鈥淚 worked on Roseanne 20 years ago and Zoe used to run around the stage with the other kids, so it was pretty clear there was a spectacular actress waiting there,鈥 he says. 鈥淏ut when she came in to read for the part of Mary, we were flabbergasted. It was beyond good luck to have an actress who is of this caliber and who has clearly mastered her craft, but also has the sensibilities we鈥檝e come to see Laurie do over the years on Big Bang. It was a tremendous piece of good luck for the show.鈥

Young Sheldon premieres Monday, September 25, at 8:30pm ET/PT on CBS.
