Ryan Murphy’s upcoming FX drama pilot “Pose” has added four more to its cast, including frequent Murphy collaborator Evan Peters and “Orphan Black” alum Tatiana Maslany.

Along with Peters and Maslany, Kate Mara and James Van Der Beek will also star in the new series, which is described as a period piece set in the mid-’80s in New York City, examining the juxtaposition of several segments of life and society in Manhattan: the emergence of the luxury Trump-era universe, the ball culture world, and downtown social and literary scene.

Peters and Mara will play New Jersey couple Stan and Patty, who get sucked into the glamour and intrigue of New York City in the 1980s. Van Der Beek plays Peters’s financial kingpin boss Matt. Maslany plays a modern dance teacher who takes a special interest in the talent of Damon (Ryan Jamaal Swain). Choreographer Ryan Heffington will choreograph Maslany’s and Swain’s dance sequences, while Leiomy Maldonado and Danielle Polanco will choreograph ball scenes for the show.

Peters currently stars in the seventh season of Murphy’s “American Horror Story,” with Peters having appeared in every season to date. He will next star in Bryan Buckley’s film “Pirates of Somalia,” alongside Al Pacino and Barkhad Abdi. Peters is also known for his role as Quicksilver in the 20th Century Fox-Marvel “X-Men” films, a role he will reprise in the upcoming film “X-Men: Dark Phoenix.”

In addition to her Emmy-winning role on “Orphan Black,” Maslany recently starred opposite Jake Gyllenhaal in the film “Stronger,” based on a memoir by a Boston Marathon bombing survivor. “Orphan Black” wrapped its fifth and final season on BBC America earlier this year.

Mara has starred in films such as “Brokeback Mountain,” “Shooter,” “We Are Marshall,” and “The Martian.” On the TV side, she starred in the first two seasons of “House of Cards” and in the first season of “American Horror Story.”

Van Der Beek is best known for his starring role in the classic teen drama “Dawson’s Creek,” as well as the starring role in the high school football drama film “Varsity Blues.” He currently stars in Viceland’s first original scripted series “What Would Diplo Do,” based on the life of the famous DJ. He will next be seen in Alexander Payne’s film “Downsizing,” where he stars alongside Matt Damon, Christoph Waltz and Kristen Wiig.

Peters is repped by CAA and Ziffren Brittenham. Mara is repped by UTA, Mosaic, and Stone, Genow, Smelkinson, Binder & Christopher, LLP. Van Der Beek is repped by Paradigm. Maslany is repped by ICM and The Characters in Canada.

The four round out a cast that includes Tony Award winner Billy Porter and the largest number of transgender actors in television history to have series regular roles. Murphy co-created the drama with Brad Falchuk and Steven Canals, who will executive produce with Nina Jacobson, Brad Simpson, and Alexis Martin Woodall. Canalis has been writing scripts with Our Lady J and Janet Mock. Michael Roberson and Twiggy Pucci Garçon are serving as consultants to the series on ball culture, an LGBTQ subculture rooted in 19080s nightclubs. Hector Xtravaganza, Skylar King, and Sol Williams will also serve as consultants. Trans activist director Silas Howard will serve as a co-exec producer on the show, which will work with Ryan Murphy’s Half Initiative to bring in trans directors for mentorship opportunities. The pilot, produced by FX Productions and Fox 21, will begin production in New York in November.
