The 30-year-old actor and 34-year-old actress, who co-starred in Murphy's show American Horror Story: Murder House, have joined the new FX series, along with James Van Der Beek and Tatiana Maslany, according to Deadline.
Pose examines "the juxtaposition of several segments of life and society in New York" in the 1980s. The Hollywood Reporter said Peters and Mara will play New Jersey couple Stan and Patty, who "get sucked into the glamour and intrigue" of New York, with Van Der Beek as Stan's "financial kingpin boss" and Maslany as "a modern dance teacher."
Deadline reported Wednesday that Pose will feature the largest-ever cast of transgender actors in series regular roles on a scripted series. MJ Rodriguez, Indya Moore, Dominique Jackson, Hailie Sahar and Angelica Ross were recently cast after a six-month search.
"We are thrilled that Pose pushes the narrative forward by centering on the unique and under-told experiences of trans women and gay people of color," series co-creator Steven Canals said.
Peters has starred in all seven seasons of American Horror Story, and is also known for playing Quicksilver in the X-Men movies. Mara portrayed Zoe Barnes on House of Cards, with Van Der Beek known for Dawson's Creek and Maslany for Orphan Black.
