THE Big Bang Theory’s Jim Parsons has revealed why he’s never taken a role on American Horror Story.

The 47-year-old played Sheldon Cooper in the hit CBS sitcom, and most recently appeared in Ryan Murphy’s Netflix mini-series, Hollywood.

Jim has worked with Ryan – the creator of American Horror Story – on other occasions but has never appeared in the hit anthology series.

Ryan, 54, regularly collaborates with the same actors but Jim admits he has never asked him to be in American Horror Story.

He told Collider: “Whether it was because of Big Bang or not, and time schedules and stuff, it had never come up.

“I had done the Normal Heart movie with [Ryan], and then he produced The Boys in the Band for Broadway. And so, those are my two major things with him.

“But no, another topic like that had never come up, which was part of the reason that I was so pleasantly surprised when he came to ask [about Hollywood], and why I felt myself jump at it.

“It was so out of left field, but it felt natural. It felt like a gift, and that’s exactly what the experience turned into.

“That’s not to say that every day was roses, but it was much more fun and rewarding than I would’ve ever guessed it to be.”

Jim played talent agent Henry Wilson in Hollywood, which follows a group of aspiring actors in post-World War II Tinseltown.

Featuring a combination of real life and fictional characters, it reimagines how the Golden Era of Hollywood could have been.

Meanwhile, season 10 of American Horror Story has been delayed until next year due to the coronavirus pandemic.

Each season of the anthology series has a different theme, with Ryan dropping big hints the 10th one will be based around the ocean/beach.
