Short answer: Yes on Spock, probably no on Sylar.
"I've been in touch with ['Heroes'] creator Tim Kring over the years and he told me they were doing it and left the door open for me but the trouble is my availability," Quinto said. "I don't know it would even be possible."
Or wanted. Quinto also sounded a conflicted note: "Heroes" made him a star but he may be ready to move on.
"That opportunity changed my life completely and sent me on a path I might not otherwise have been on, but at the same time, I'm very interested in forward momentum. I'm very interested in diversity. I'm very interested in expanding peoples' expectations of me, defying expectations of me," he said. "And I don't know that going back to such an definitively iconic character would necessarily do that, so it's a larger question I haven't had to answer yet because no one has given me an offer or circumstances. We'll see. I know that whether or not I'll be involved, I'll be excited to watch it."
Quinto has no plans to return to the currently-in-production season of FX's "American Horror Story" but he will be back on the big screen as Spock in the third "Star Trek" film, which is set to be directed by previous "Trek" movie writer Roberto Orci and released in 2016, the 50th anniversary of the TV debut of the original "Star Trek."
"It's in the preliminary stage now of the script being finished and polished and I imagine the phone will be ringing sometime in the next few months to talk about when we'll go back to production," Quinto said.
The plot of the next film is under wraps but Quinto dropped some hints.
"The five-year mission [of the U.S.S. Enterprise] will be a part of the next film in some way or another," Quinto said.
"We're coming up on the 50th anniversary of one of the most iconic sci-fi series in history of the entertainment industry so I think it's inherently an ongoing story but I think we'll feel some sense of evolution in these characters that's been building through the first two films."
Quinto's participation in the third film was never actually in doubt but after that movie it's an open question.
"We all signed on for three movies so we're coming up to the conclusion of that commitment," Quinto said. "It will be interesting to see how our relationship to the franchise evolves beyond that point."
