American Horror Story: Hotel has been difficult for show runner Ryan Murphy to write, by his own admission.

Murphy, who is also producing the highly anticipated new horror comedy series Scream Queens for Fox this fall, spoke with The Hollywood Reporter recently about both series.

The multi-hyphenate compared the two series and revealed how this season of American Horror Story has been a challenge.

"It's fun to write Scream Queens but challenging to write Horror Story, particularly this season, which is about a personal fear and phobia that I have that I haven't explored since the first season of Horror Story because it f---ed me up and I didn't want to write about things I was scared of - but I wanted to go back to that," Murphy explained.

It is unclear which element of the first season Murphy is referring to, though fans of Murder House (which the season would later be named) will surely be happy to hear this news.

American Horror Story: Hotel features an incredible cast that includes Lady Gaga, Sarah Paulson, Evan Peters, Kathy Bates, Angela Bassett, Finn Wittrock, Denis O'Hare, Matt Bomer, Wes Bentley, Cheyenne Jackson, Chloë Sevigny and Max Greenfield.

Filming reportedly begins this week, with O'Hare tweeting that he was scheduled to come in on Monday.

American Horror Story: Hotel is set to premiere in October on FX, though the network has not yet announced a specific premiere date.
