Speaking to The Wrap, Murphy told that Hollywood shut down due to the global health crisis would impact the upcoming installment of the series in more than one way. Not only expect a delay in the release date but also change in the original plot idea.

According to Murphy, the original idea for season 10 of "American Horror Story" needed to be filmed during the warmer months. Since there is still no specific date when the crew and cast can go back to shooting the next season, the showrunner suggests he may have to make changes or wait longer.

"Well I don't know, because a lot of what I was going to shoot was dependent on a very specific moment, it was a weather-dependent show," Murphy explained. "So now I don't know. I don't know what we're going to do. I don't know what I'm gonna do next with that show. I don't know if I'll accelerate another season or wait till next year to shoot this one," he added.
