Writer-producer Ryan Murphy revealed Thursday that Matthew Morrison will play a role in his FX series, American Horror Story: 1984.

Morrison previously starred in Murphy's musical dramedy, Glee.

Murphy posted on social media a pair of "camera test" videos for Season 9 of AHS, showing the cast variously dressed in 1980s-style dance gear such as leotards, half shirts, tights, leg warmers, and sneakers as they warmed up in a studio, then costumed as summer campers in shorts and tank tops as they walk through a rustic cabin.
