Zachary Quinto is slated to guest star in four episodes of the new FX series "American Horror Story" as a recently deceased gay man.

Quinto, who recently came out as gay, is mostly likely known for his roles as the villain Sylar on the "Heroes" television series and as Spock in the 2009 "Star Trek" film.

In "American Horror Story," which was created by "Glee" executive producers Ryan Murphy and Brad Falchuk, Quinto will portray Chad, the former gay owner of the haunted house who befriends Vivien (Connie Britton).

The actor will make his first appearance in Wednesday's episode, which is the first of a two-parter, the second episode will air on Halloween night. There will also be a marathon of the first four episodes leading up to the October 31 showing.

The gruesome horror series has received rave reviews and was one of the most-watched cable series on Wednesday, with 2.59 million viewers, according to The Hollywood Reporter.

The 34-year-old actor gave an interview to New York magazine about his latest film, "Margin Call," and said that it was his role in the Broadway revival of "Angels in America" as Louis Ironson that made him realize how important it was to contribute to the gay community.

The play is about people and their loved ones dealing with AIDS in the mid-1980s. Quinto said that his eight-month stint in the play was "the most challenging thing I've ever done as an actor and the most rewarding." He added, "And at the same time, as a gay man, it made me feel like there's still so much work to be done, and there's still so many things that need to be looked at and addressed."

Previously, the actor had remained quiet about his personal life. The magazine notes a profile of the actor from the New York Times in 2010 where Quinto talks about his passion for gay rights and The Trevor Project but added that although " the blogosphere is rife with speculation about his sexuality," Quinto "prefers not to feed that rumor mill with either substantiation or dismissal."

Last year, Quinto recorded a video for the "It Gets Better" campaign, which includes videos from celebrities and non-famous people offering encouraging words to those bullied about their sexuality. It was started last year following a slew of suicides of bullied gay teenagers.

The actor recently played Anna Farris' boyfriend in the comedy "What's Your Number?" In the past, he also appeared as Tori Spelling's gay best friend on "So NoTORIous." The actor is set to reprise his role as Spock in the upcoming "Star Trek" sequel, which is still in the works.

Zachary Quinto's debut on "American Horror Story" will air on Wednesday at 10 p.m. ET on FX. Watch a clip below.
