Actor Neil Patrick Harris had a memorable guest spot in the first season of Glee, and now he wants to be in another Ryan Murphy-created show: American Horror Story.

American Horror Story: Freak Show Will Be "Unlike Anything" The Series Has Ever Done

Harris spoke on EW Radio about how he wrote a letter to Murphy about potentially appearing on American Horror Story: Freak Show.

"I wrote a letter to Ryan asking if I can be in it, even though I wasn't even available to be in it...I just love those series and Coven was fantastic...to do one that involves any kind of freak, circus nonsense is going to be so unsettling to watch. Can't wait!" he raved.

This letter had gone unanswered by Murphy until now, with the executive producer tweeting to the How I Met Your Mother alum offering him a role:

"@ActuallyNPH of course you can be on Freak Show! I have a role I think you'd love."

Murphy's tweet was retweeted by over 800 accounts and favorited by over 1,000.

Harris previously won an Emmy for his role as Bryan Ryan, Will's (Matthew Morrison) nemesis in the first season of Glee.

American Horror Story: Freak Show is set in the 1950s and centers on one of the last remaining freak shows in America. Jessica Lange's character owns the freak show, which features "freaks" played by Sarah Paulson, Angela Bassett, Kathy Bates, Frances Conroy and Evan Peters. Could Harris join that list?

American Horror Story: Freak Show is slated to debut in October on FX, though the network has not yet announced a specific air date.
