Sheldon Cooper actor Jim Parsons speaks for first time since wedding about new Young Sheldon show

Big Bang Theoryā€™s Sheldon Cooper is set to get his own spin-off show.

Young Sheldon will follow the life of a boy Sheldon Cooper as he grows up in deepest Texas.

And Jim Parsons, the worldā€™s highest paid gay actor, is set to star in the show as its narrator.

Parsons, who married his long-term boyfriend in a stunning ceremony last week, has now spoken for the first time about the project.

The show will follow him battling with his right-wing family, long before he finds the freedom of geekery and his Big Bang Theory friends.

He praised the actor behind the characterā€™s younger self, Iain Armitage.

He told ET Online: ā€œWe saw lots and lots of tapes and we saw lots of auditions and thereā€™s something about Iain that just popped immediately,ā€ Parsons told the channel.

ā€œThere was no denying it as soon as you saw his face and he handles the language well and he memorises easily, and the biggest thing of all is heā€™s just an excellent actor. I donā€™t know how someone so young acts so well.

ā€œI didnā€™t when I was his age, but he does.ā€

Armitige, who previously starred in Big Little Lies, revealed what itā€™s like to work with Parsons, saying: ā€œWe sort of buddied together and sometimes it would range from stuff like, ā€˜Say this line a little differently because Sheldon would think of it differently.ā€™ ā€˜Donā€™t smile,’ā€ the child actor revealed.

ā€œHe really didnā€™t need very much help,ā€ Parsons added.

ā€œIn some ways, heā€™s too good of an actor, at first blush, with the material.

ā€œHeā€™s listening too well. Heā€™s being too empathetic, which is really good acting but not in this case.

ā€œThere were just a couple things you had to curb, like, ā€˜I know you want to laugh and smile and be nice to people [but] donā€™t do that anymore!’ā€

The new show is set to air on CBS in mid-September.

It comes after the cast of the original show offered to take a pay cut to increase the pay of two female colleagues.

Itā€™s been revealed its five biggest stars have offered to take a pay cut of $100,000 an episode ā€“ so that two female stars can increase their salaries.

The five originals ā€“ Jim Parsons, Johnny Galecki, Kaley Cuoco, Kunal Nayyar and Simon Helberg ā€“ have agreed to their salaries being lowered.

It should mean that female co-stars Mayim Bialik and Melissa Rauch, who joined in the third series of the hit show, will get a raise in their pay.

Jim Parsons is thought to be the highest paid gay actor in the world, raking in $1m an episode.

Their million dollar an episode salaries are now as high as Friends, where the cast also negotiated to get each otherā€™s salaries increased.
