Ryan Murphy is a bit of a television juggernaut at this point. He's been working with Fox and FX since 2003, and currently has five shows working between those two networks. He's also just penned a deal to work with Netflix, meaning that his particular film sensibility will be around for many years to come. Murphy often pulls from the same pool of actors when casting his projects, which is why actors like Finn Wittrock have popped up in both American Crime Story and American Horror Story. The latter is perhaps what the actor is best known for, especially his horrifying run as Dandy in Freak Show. So will Wittrock return to AHS? Here's what he said,
I don't know. I would love to. I am committed to staying in the Ryan Murphy universe as long as he will have me.
While it doesn't look like Finn Wittrock has any concrete plans to join the mysterious seventh season of American Horror Story, his comments to EW indicate he'd be more than happy to return to the anthology series if Ryan Murphy asked. Hopefully that will be sooner, rather than later.
Finn Wittrock joined American Horror Story in the show's fourth season, Freak Show. He played the season's big villain, privileged serial killer Dandy Mott. While Twisty the Clown originally seemed to be the primary antagonist, he eventually revealed a backstory that made him a sympathetic character. Dandy had no redeeming factors, and died an appropriately awful death.
The actor would go on to play duel roles in Hotel, before becoming a more tertiary presence in the series with AHS: Roanoke. The most recent season, Cult, strayed away from many of the show's traditions, including bringing on a brand new cast of actors (with the exception of Sarah Paulson). Will future seasons once again bring back the ensemble cast of actors? We'll just have to wait and see.
While Finn Wittrock seems to have distanced himself a bit from American Horror Story, he had a truly heartbreaking arc in the most recent episodes of American Crime Story: The Assassination of Gianni Versace. He played Andrew Cunanan's original victim, Jeffrey Trail. TV audiences had to watch as Jeffrey came to the realization that something wasn't right with Andrew, just to be brutally killed by the serial killer.
Although fans are no doubt hoping that Finn Wittrock would return for another season of American Horror Story, Ryan Murphy's Netflix deal means that there are going to be even more Ryan Murphy projects in the works. As such, the producer/writer may call on Wittrock to originate a different role, therefore making him unavailable for AHS. We'll just have to see how long Murphy plans on keeping the anthology series running, while juggling his myriad other projects.
